I love streaming music services. Mog, Rdio, Spotify. They’re all great. They help solve one of the most vexing problems of being a musician, discovering new music (without going broke buying stuff). One issue that always comes up, though, is finding an exact recording. Each service has a pretty large catalog, and while there is some overlap, each service has many recordings that the others don’t. Enter: Music Smasher by Matt Montag. It searches Rdio, Spotify, Grooveshark, Soundcloud, Mog, and Bandcamp (whew!). What is really cool about the service is that it includes services like Soundcloud and Bandcamp, where files are uploaded directly by artists and catalogs often include independent artists and “unreleased” content. Go there now.
