The Night, Kai and Marina have all been my favs. It might be a bit surprising but I really like to exercise to this album. I dance/exercise in my room and I find Kai and the drum rhythms can really get me moving! The music and lyrics are really mysterious and so my imagination starts to wander, and I like that a lot as I try to forget that I'm exercising, and just focus on expression. The slower tracks are great for stretching too.
