Try it here for yourself. Store your music and other audio somewhere other than your pocket.
I'm uploading some music, a library or two and some airchecks. 5gigs for free right off the bat, buy an LP from Amazon and get 20gigs. More space is available, for an extra charge. Accessible from PC's and Mac's and Android powered devices, only MP3 and AAC files allowed. Legal foo-foo is currently in place, but it'll work out.
Kimda cool: the ap just sweeps through your HD and sucks up every tune in the allowed formats and stuffs them in your online folder. Listen thru the Cloud Player.
