Google music works great! I forgot I even had it loaded after I installed the mac part when it first came out. But it didn't forget about me... it had quietly uploaded all my iTunes music, and playlists.
So when I got my Nexus 4 I was pleasantly surprised to see all of my music, ready to play whenever I wanted. Sweet.
I was an iTunes Match user since it first entered beta last year. But I just let my subscription lapse as I won't be using it anymore.
