Pandora is my choice for music

I’ve been around the bend from Pandora, Slacker, Spotify, MOG and Rdio. I’ve tried them all and I’ve come to the conclusion that Pandora is the service for me.

The other services require too much work on my part to operate and setup my playlists. With Pandora, I can be lazy and just let it play whatever comes up in my station. I can shuffle the stations around and thumb up and down tracks as I choose.
Plus, for $36 a year for Pandora One I get ad-free music compared to $120 for the others (that’s for the $10 mobile package on Spotify, MOG, Slacker, Rdio)
I know Pandora isn’t for everyone, but for me it’s plenty. What service do you use?
