Cool new Google Music launch for users in the US. You can store up to 20,000 of your tracks for free, and, with Universal, EMI, Sony and a 1000+ Independent music labels on board, discover and purchase millions more. You can even share a full free play of any song or album purchased in the store with your circles. Check out this fun HTML5 based tour from your Chrome browser http://music.google.com/about/tour and the blog post is below.

Not in OZ yet, but might try to get on it with a VPN.
The sharing through google+ thing looks pretty awesome.

I've signed up and downloaded the music uploader all ok with a VPN but a mate is saying for him its asking for a US credit card.

Got about 160gig worth of music and that was only 17000 songs. Goddam. I don't think it checks if its an essential mix ;)

If it's anything like Google books it will suck.

Don't say that!

Both are in their infancy, so they might get better!

What's not to like about storing 20000 songs online for free?

Well you won't find Britney if you don't upload any of it to your account.

Google Music will only return results music you've bought or uploaded. Google Books searches a repository of books, it's not the same thing.
