Not really the same, but...

I have Sirius sat radio in my car. Thrown in with the plan, you get all the channels on your phone (app) and computer as well.

You get every station, plus more that aren't on the car radio.

Obviously you don't get to build your own playlists, pick individual songs, etc. But honestly when I had Spotify, I'd build myself a playlist and after 1 or 2 playthroughs I am bored with it. Sometimes it's nice just to pick a genre you want to listen to and let the DJs pick the songs...not so much work.
