Music Smasher is a smash up of popular music streaming service APIs. I developed it to simplify the task of searching across Spotify, Rdio, Grooveshark, and other catalogs to find out who has the music you love, giving you more information for choosing a streaming service.
Music Smasher is currently hosted at mattmontag.com/smasher.
Note that due to differences in the APIs, the result counts aren't telling the whole truth (especially for Grooveshark ). I hope I can fix that.
Please post any problems or suggestions in the comments.
Technical notes coming soon.
Music Smasher has been pretty useful during regular Spotify browsing. Today I learned Spotify doesn't have any Antiloop, Mark Ronson's Bike Song, or any of the Fabriclive series.
Results are now linked to for streaming. Rdio tracks that are unavailable for streaming or download will no longer show up in results.
