Old Vinyl by fensterbme

The world of online music is growing rapidly.  Every day, thousands of new tracks by new artists are uploaded to the Internet. Soon all recorded music will be online and available for you to listen to anywhere at any time, on any device.

However, this seemingly endless supply of new music creates a problem for a music listener. How can you find music that you will like when there are millions and millions of tracks to choose from?

In this blog, I write about the world of online music discovery and recommendation.  I look at the tools available to help people find music.  I examine some of the issues that can make music recommendations go bad.   I also write about things that I find generally interesting including programming, data visualization, playing games,  and (of course) music.

    I read your blog about the drummers that use clicktracks in the studio, have you tested songs from Rush and Neil Peart’s drumming?

      Paul, you seem to have a long experience in music recommendation. All streaming services offer a huge catalogue of music with millions of songs, but when I try to listen to some new music that sounds similar to what I know and like, not one offers the user a way of interacting, for example to enter a seed song and generate an auto playlist based on the acoustic fingerprint and not on genre or similar artist. Maybe I expect too much, or am not aware of who offers this, or how to do it, but a real world app or service that works without being a hacker is missing. Thanks for helping, and sorry if I posted this in a wrong blog or format.

    Hi Paul,

    I also stumbled on your blog after reading about the click track post. I really enjoy everything you’ve written so far.

    I have a blog where I post a new drum loop everyday and a question has arisen in an area where you seem to have some expertise in:

    http://ryangruss.com/?p=1320

    Basically, are there any current methods for converting an audio track into a transcribed piece of music. Much like audio to text conversion, but obviously much more complex. Would love to hear your thoughts!

    Thanks,
    Ryan

      ryan:

      It is not a solved problem, but it is a very active area of research. Google for “ISMIR transcription” to see the state of the art.

    i stumbled across this blog from your sun blog post on the api for yes.com. i was annoyed that the website didn’t have an rss feed for song logs or other such easily exportable format. (i had to go select a station, date, hour, click submit, change hour, submit…) then i saw the link to come over to this blog and yow. this is such interesting stuff. keep up the interesting posts!

    Hi, re Spotify – My other half is worried about using it because it’s peer to peer, but does that mean people are playing music from my pc ? like – sharing, in the way we usually do with peer to peer.
    I thought the music files are all at a Spotify server.
    And no chance of viruses ?

    cheers !

    • #7 by plamere on April 16, 2009 - 7:24 am

      @troy – a bit off topic? but no, spotify does not serve music from your PC to other people.

    Ryan and plamere,

    You may want to check out Melodyne, which recognizes audio as notes and can treat it like MIDI. I don’t know if it can render that info into a transcription or not. Hope this helps.

    Dear Plamere,
    Apart from subjects on this page I have seen your article: Searching for music by melody or rhythm, with the statement: (about Musipedia) The best query-by-melody, and query-by-tapping site I’ve seen.
    This was in 2006
    You might not yet have seen the Melodycatcher.
    We think this tool is clearly better (more accurate)
    but undoubtedly you can better judge that for your self.
    All questions, comments and suggestions are welcome.
    “We” is Florian Bomer and my self, as you can see on the website under “About”

    Best Regards
    Jan van Os

    Paul…. great blog. I was also at Music & Bits, and so I think it’s great you recapped Brian’s talk.

    I was wondering if you’ve heard of a really simple online tap-metronome (preferably using Echo Nest) where I can tap in a beat for 20 seconds..and return the average. Do you think that is how EN would work – it’d be the avg? Or would it maybe just choose the first 5 seconds and decide the BPM?

    Thanks!

    Hi Paul – What happened to Snapp Radio? I loved that site? Is there anything similar you know of??

    Paul,

    I’ve read your music recommendation app reviews over the years with interest, and mostly agree with your findings that most disappoint.

    I’ve just heard about the youtube music recommender (http://www.youtube.com/disco) – I’d be really interested to hear what you think of it.

    Can Google can bring the kind of crowd analysis to music discovery that they bring to translation and search (http://googleblog.blogspot.com/2010/01/helping-computers-understand-language.html)?

    (Sorry about abusing the about page, not sure how else to contact you)

    Are you going to be doing the SXSW Artist Catalog this year? It was really helpful. If not, do you still have the code? Somebody should keep it going.

    • #17 by Paul on February 11, 2010 - 11:29 am

      Yeah – look for it around March 1

  13. #18 by Webby on May 26, 2010 - 6:56 pm

    Your music engine might need updating…
    I did link between Itaal Shur and Carlos Santana — it should have been one degree of separation, they cowrote “Smooth” and won a Grammy for it.
    Your program had it at 10 Degrees…

    hola, Hi, in Bogotá Colombia, I´m so happy wen a discover your musicmaze, the first vesion was simple but is a god idea… I hope that the new vesion still god and better….. congratulations

    In case you’re interested, I’ve created a free smart playlist based system for iTunes that will learn song ratings over time as well as vary the play frequency based on those ratings. Just the thing for organizing huge libraries. Only had a couple people download it, but they seem to like it so far.

    Just tried out ‘ 6 degrees of black sabbath’ ; Todd Rundgren to Ian Tyson, curious to see where it took me. it charted a path that went through Rambling jack Eliot to Corb Lund etc.I believe that back in the early seventies Todd Rundgren produced the Ian and Sylvia Tyson album’ The Great Speckled Bird’ I may be wrong but I thought you might like to know. Cheers.

    Yes, it’s really hard to choose what music you will listen to if there are millions of tracks to choose from. For me, I often watch TV shows on music channels.

    Hi Paul, thank you for all the information and research. Keep up with the writing!

    It is a pity that Infinite Jukebox does not work in some browsers. By the way, is it possible to save a copy of the generated output of Infinite Jukebox? In other words, can Infinite Jukebox save each new result as a downloadable mp3 file?

    • #24 by Paul on November 26, 2012 - 11:29 am

      no – sorry it is not possible to save the output. An infinitely long song would be too large to fit on all of the world’s hard disks

      • #25 by SoundEagle on November 26, 2012 - 3:31 pm

        That goes without saying! It would be really nice if Infinite Jukebox could have a “Save” feature to allow the user to save as much or as little of the output data on his or her storage device(s).

    Paul, Hi.

    My name is Jesus Herrera and I am just an amateur audiophlie.

    I also have a (very humble) Blog at WordPress, which mainly focuses in reviewing songs, trying to analyze why I like them.

    https://lacanciondelasemana.wordpress.com/

    Your post “The Looudness War Analyzed” was a true eye (ear) opener for me, thanks.

    Would you allow me to put a link on my Blog to yours? I think it might be valuable for my readers.

    Thanks. Greetings from Mexico

      Of course. — Paul

    There are so many clever tools on here. One I particularly like is the Map of Music Styles. How hard would it be to adapt this to highlight your own music library based on Spotify for example? And then create a playlist using the Boil the Frog algorithm by selecting one or more nodes?

  21. #29 by Rick Bolton on August 12, 2013 - 1:06 pm

    Hi, Paul… I’ve admired your work from a distance, and would love to initiate a conversation with you regarding discovery paradigms. I am working on film and television content discovery, which is totally different from music discovery, of course, for many obvious reasons, but I think we still have some things to talk about! Please drop me a note at my email address (provided to you via my login here)… hope we can connect soon.

  22. #30 by Dominic on November 20, 2013 - 7:21 am

    Hi Paul,

    Nice blog – I particularly enjoyed your post about the Hackathon in Finland.

    I write for Xyo’s mobile apps and games blog (http://xyo.net/blog/) and I’m writing an article about the best apps for making, recording, performing, and listening to/discovering music, and, as you’re a music lover, app hacker and someone who is interested in the tech-based side of music I thought I’d write to see if you’d be willing to share some of your wisdom.

    Please let me know if you’d be up for a short interview.

    Hope to hear from you soon,

    Dominic

    Very informative and interesting blog you have here. Thanks for your efforts, will follow.

    When I initially commented I clicked the “Notify me when new comments are added” checkbox and now each time a comment is added I
    get several e-mails with the same comment.
    Is there any way you can remove people from that service?

    Thanks!
