But I had assumed that almost everyone uses it now. Or maybe it's less popular than in the iPod days, because the phones/ipads are more independent.
My friend just recommended a podcast, and I didn't even realize that iTunes is where you get a lot of podcasts! I've never even tried.
Anyway, for buying music, I use Amazon's MP3 service and recommend it. You just download the album as a .zip file. Then I put it on my own music server. (I guess this is another reason I'm a dinosaur; I prefer listening to an entire album over streaming individual songs.
I switched to Spotify for awhile, but the quality was noticeably bad on my speakers. I use Sonos and when hooked up to good speakers, you can really tell. Amazon MP3s sound indistinguishable from the original recordings. And even streaming Amazon music, but not Spotify.
