I have 2 invites for the beta. It lets you upload 20,000 songs and listen to them with any browser anywhere and on most devices
like I said, only 2 invites. So unless you are seriously going to use it. Dont request an invite.You can get to your personal music collection at home or on the go. Listen from the web or your Android 2.2+ phone or tablet with the Music app available from Android Market. Not online? No problem. You can select the specific albums, artists and playlists you want to have available when you're not connected. And the songs you've recently played will automatically be available offline.
