You know - there is an alternative here.
I subscribe to MusicNow (www.musicnow.com) which doesn't always have ALL of the latest songs but is pretty good about keeping up, offers $.99 cent purchases, excellent radio stations and unlimited access to a HUGE variety of music, all for $9.95 a month.
It's integrated directly into WMA (which I like because I can switch between the two seamlessly). Still, I will take a quick look at iTunes - if nothing else, I still bleed six colors.
