Today at Google I/O 2011 in San Francisco they announced Google Music, a new cloud service that lets you host your musical collection online so you can listen to it anywhere, even offline. It also makes it easy to keep your music sync without using cables, file transfers or storage space limitations.
The service is launching in beta today, allowing storage of up to 20,000 of your songs for free (at least while it’s in beta.), but you can request an invite.
