Spotify Web API

Say Hello to Spotify's New Web API

Still no track level play data which bums me out.
This is really big news on the Spotify front. Their previous web API was really sparse (just search and album info) whereas this is a full blown API. Finally being album to access a users playlist data opens up a lot of possibilities for apps (the simplest of which being export). Because apps no longer need to go through the Spotify app approval process I suspect we'll see a lot more interesting web based apps.
