I make up my own playlists of music I enjoy. BUT, my favorite cycling workouts are The Sufferfest. You can only get them as downloads, and they are more cycling than spin (that was an adjustment), but I find them tremendous fun and whew, do you burn the calories. They are advanced workouts, so Cathletes will feel right at home.
When I say they're different that spin, it's because you're not changing positions as much...it took me a while to get used to spending so much time in the saddle. When I first started, I'd just stand whenever I wanted to. I also found that it works my quads differently than pure spinning...not better or worse, just different. I'm all for cross training.
FYI, these workouts have great music and feature pro cycling footage. Each workout has a story of sorts and lots of humor, all intended to push you to go harder.
The workouts are relatively inexpensive, about $13 each, so if you're at all tempted, try one out. I caution you not to try one of the $8 workouts for your first effort....they are meant to be used on combo with the existing workouts and don't have warm ups or cool downs. And one, called The Long Scream, will make you do just that if you're not already used to the SF, at least in my opinion. Anyway, give it a try, and you may become as addicted as I am.
FYI for you Sufferlandrians out there, the new Sufferfest is coming out next week...112 minutes of suffering. It's called Blender and was designed by Taylor Phinney's coach. Heaven help us! Of course, I can't wait!
