Music Player

I wanted to do a music player for learning purposes. The initial thought was to redesign Spotify. At least, that was the plan. The end result is somewhere in between Rdio and Spotify in both functionality and design.

I've made two versions, one with a dark player, and one with a light player. The layout on the top bar is different on both. I'm curious which one you guys/gals like better and why. Never to old to learn! Right? ;)
