Yesterday, Steve Jobs reminded us that it was less than 10 years ago when Apple announced the first iPod which could put a thousand songs in your pocket. With the emergence of cloud-based music services like Spotify and Rhapsody, we can now have a virtually endless supply of music in our pocket. The ‘bottomless iPod’ will have as big an effect on how we listen to music as the original iPod had back in 2001. But with millions of songs to chose from, we will need help finding music that we want to hear. Shuffle play won’t work when we have a million songs to chose from. We will need new tools that help us manage our listening experience. I’m convinced that one of these tools will be intelligent automatic playlisting.
This weekend at the Music Hack Day London, The Echo Nest is releasing the first version of our new Playlisting API. The Playlisting API lets developers construct playlists based on a flexible set of artist/song selection and sorting rules. The Echo Nest has deep data about millions of artists and songs. We know how popular Lady Gaga is, we know the tempo of every one of her songs, we know other artists that sound similar to her, we know where she’s from, we know what words people use to describe her music (‘dance pop’, ‘club’, ‘party music’, ‘female’, ‘diva’ ). With the Playlisting API we can use this data to select music and arrange it in all sorts of flexible ways – from very simple Pandora radio style playlists of similar sounding songs to elaborate playlists drawing on a wide range of parameters. Here are some examples of the types of playlists you can construct with the API:
- Similar artist radio – generate a playlist of songs by similar artists
- Jogging playlist – generate a playlist of 80s power pop with a tempo between 120 and 130 BPM, but never ever play Bon Jovi
- London Music Hack Day Playlist -generate a playlist of electronic and techno music by unknown artists near London, order the tracks by tempo from slow to fast
- Tomorrow’s top 40 – play the hottest songs by pop artists with low familiarity that are starting to get hottt
- Heavy Metal Radio – A DMCA-Compliant radio stream of nothing but heavy metal
We have also provide a dynamic playlisting API that will allow for the creation of playlists that adapt based upon skipping and rating behavior of the listener.
I’m about to jump on a plane for the Music Hackday London where we will be demonstrating this new API and some cool apps that have already been built upon it. I’m hoping to see a few apps emerge from this Music Hack Day that use the new API. More info about the APIs and how you can use it to do all sorts of fun things will be forthcoming. For the motivated dive into the APIs right now.
