Would you pay it? What are the alternatives? I'm not a huge Pandora fan - ads and limited skipping. Spotify sounds interesting but sleezy, and I just heard about something called Grooveshark I'm looking into. But I'll have to say, I loved Last.fm as long as I had strong 3G. It usually played songs I liked, and I was amassing quite a library and discovering music regularly. So what do you people think?
