Ok this is just iLike and Lala widgets embedded in the search results. It's not a new business model, it's not new technology or a new experience. It's the same old music you can find anywhere else. Can we move along now?
It will be if they release a HTML5 & Google Gears web app competitor to iTunes in addition to embedding the music player in search results.
Agreed that this really isn't a big deal. However, if it's a step along the path to having some kind of streaming music integration in Android, that would be new. Total speculation.
