thanks. Updated.

That’s great – if you make this available in JSON, one could probably write an automated MHD-ideas generator ;-)

http://tuneefy.com uses a lot of them ;)

Hi Paul,
nice list. how would you define ‘Music APIs’?
your list of tools at http://music-ir.org/evaluation/tools.html was good too.
best, piem

Yes has been discontinued and is succeeded by http://rew.fm/. The site is intact but the api doesn’t work anymore.
Eg. http://api.yes.com/1/station?name=WFNX

pandora.com : http://pan-do-ra-api.wikia.com/wiki/Json/5
musicme.com: it’s called Axe, but I couldn’t find a link.
http://www.dessbox.com/start.php : uses Youtube API, however

#12 by Arpege Music on April 17, 2014 - 4:26 am
Thank you to add ‘Pizzicato’ (http://www.arpegemusic.com) in ‘Miscellaneous’ and if you want to add a heading called ‘Display/Music Software Creation’, there is ‘Music Notation Library’ (http://www.music-software-development.com).

Useful list! Been around the net to look “Music API” php class which is open source and well developed.
#18 by Jeremy on February 28, 2015 - 2:12 pm
Hey Paul, cool website and looking forward to connecting with you directly. It looks like ArtistLink is shutting down as of today. Should it be removed from the list?
#19 by Tony on March 3, 2015 - 3:21 am
Hi Paul, great post! Can we submit our music ID API to this list? http://developer.doreso.com Thanks
#20 by Joe on June 16, 2015 - 4:41 am
Hi Paul, here’s another service doing audio identification, hope you can list it on your page: http://www.acrcloud.com
#21 by Ben on September 28, 2015 - 1:01 pm
Hi Paul,
Thanks so much for including Feed.fm! We’ve changed our logo. Any way I could send you the new one? Also, could you point to our homepage (www.feed.fm) rather than the developers’ sign-in?
#22 by AE on October 20, 2015 - 12:37 pm
Hi Paul, thanks for the post! Genius also has a great API for lyrics/annotation https://docs.genius.com/#/getting-started-h1

Hi Paul, Musicovery API is missing: it provides recommendations/playlists personalized in real time. http://musicovery.com/api/V3/doc/documentation.php. Thanks, Vincent
