I just want to agree that Google Music's upload function is amazing even if you never use it to listen to music. All the files I've ever owned are now permanently backed up in an offsite location for free. It was really buggy the first few years but they seem to have ironed out all the kinks lately. In general I also love streaming since it lets me try a half dozen new albums a week. I tend to find a couple new albums a month that I love that way, and they're almost never what I'd predict. As for Apple's service, I'll have to get in there and play with the UI to see if it offers anything over Spotify and G Music. I'm not particularly loyal to any service at this point. I mostly hope that we don't see massive exclusivity wars the next few years, but sadly I think we will.
