Spotify Premium (student discount @ £5 a month) and iTunes. Would probably use iTunes Radio had it become available over the pond yet.

Do prefer owning my music however, just the other day one of my favourite albums just disappeared from Spotify for no reason
 
For AT&T customers it is a great time to give Beats Music a free 3 months trial. You may only have a day or so to sign up. Also there is only an up side since we should see some changes/Apple integration within the 3 months.
 
Just the iPod app on my phone. I might use iTunes Radio more often when they add music streaming, but for now, I just use Grooveshark if I want to do that.
 
I got the promotional Sprint 6 month trial for Spotify and wow, i had been missing out.

I can just download all my fav songs to a playlist and listen to them offline.
 
I use Pandora, Spotify, and Slacker radio. What I like better with Slacker than Pandora, is that Slacker shows you how many skips you have left.
 
I buy music from itunes everynow and then but I mainly use spotify premium and 8tracks.
 
Being from Sweden, I've been using Spotify since the initial beta phase. However, I've stopped paying for a Premium subscription and now rely on iTunes Match; I love Beatles, and they ain't coming to Spotify anytime soon. I also like iTunes far more than the Spotify client for Mac. Plus it's cheaper. And iTunes has AirPlay. And...
 
I have been using Spotify, and am extremely happy with it (Although the new app update was a little too out there.) I have been hoping for Apple to have a solution, because really if Apples solution is just using the "Music" app, i'm happy. I don't need "discovery" or any of that other crap. I just want to create a playlist with the songs I like. However, with Spotify offering $4.99 to students. I will probably stick with that unless Apple comes in below that price.
