Available Music API

Question

I am wanting to develop a workout app that will involve certain types of music and I figured the easiest way to get certain genres is to see if a music app allows developers to use their API. If so I would go from there, but first I need to find someone.

Does anyone know of a Music App (Pandora, Slacker...) that will allow developers to use their API for music in my app? Or would this be better served with a Service to a music app of the users choice with a station request by me (If I can do all that from a Service)?

Answer 1

I doubt Pandora would expose much of their database to anyone for free.

Answer 2

lastfm has a public api, not sure if its free http://www.last.fm/api
