So- I dunno. I've already got all my music on Amazon cloud. the only benefit looks like more storage, which right now (I have 20GB free thru Amazon) I don't need. I like that from Amazon I can download music through the app also- there are plenty of spots here without 3G coverage, especially on the subway. Also, the article is wrong, amazon Cloud Player does have playlists. So I'm not sure how Google Music is going to be better than what I already have.
