Tori Amos, because I am a huge girl...otherwise, I am way too nostalgic for the 90's given how recent they are: the Sugarcubes, Bjork, Blur, Beck, The Gin Blossoms, Better than Ezra...if it was listened to in high school, it is on my running playlist. Also, Leonard Cohen and an undying love for anything related to the Beatles.
Don't laugh, but I also listen to way too much pop and hip hop music for my own good-I swear it is for my working out at the gym/hanging out in Jersey mixes, honest!
