What music app(s) do you use?

I don't really use anything at the moment. I've been considering a Google Play music subscription lately though. The thing is, I like good sound quality, and the only reasonable way to get that is to stick with CDs. On the other hand, I can use my connected devices in lots of places that I can't use CDs. So, I may bite the bullet and pay $10 per month to listen to poor quality audio.
