Anyone use Spotify?

I've been a Zune Pass user for a long time. MS seems like its about to kill it off and my subscription runs out next month. I've been looking for alternatives and spotify seems interesting. Anyone use it?

Only downside seems to be the method in which it downloads music(you have to make playlists, seems dumb to me).

I LOVE zune pass. I'm unfortunately not going to be using Windows Phone anytime soon and I'm worried that I might lose support for music downloads on my Zune HD. The other fear is that if I lose/break my zune its going to cost a fortune to replace it since they aren't made any longer.
