I will add to this the possibilities integrated google voice mobile function to search for specific songs.

I think it will be built in Google Musicsearch, which already exists.

Do you think Google will allow the public to submit their own audio with a preview track, thereby putting pressure on the bigger labels? In this way they can try and put themselves in a position to bargain with the bigger labels when smaller artists choose Google rather than a traditional publisher.

I'm not sure how search will feature but the optimal solution would match a person's mood/profile with different artists and sell music that way.

Great news. I think it will offer a variable pricing system though. What the Industry wants, but not what ITunes will deliver for them.

Anyone any idea when this will be released? When is the next big conference Google is participating in?
