"Created by musicians, for musicians, GarageBand.com is here to help you advance your music career," says their website. How will they do that? You can submit songs to their ongoing contests, get written feedback on the songs you've written, get listenener ratings, and possibly get the exposure you need to "get discovered" by a major label - so far, 13 artists have been signed from being "discovered" from GarageBand, and one has gone double-platinum.
