OK, this is really rad. Would love to hear more about the back-end. Seems to work really well for finding tracks! I even mis-spelled one and it was found.
My only critique from initial viewing is making the upvote/downvote more clear. It appears if you click on the top of the upcoming track, it up votes, bottom, down votes. You might want to add a little arrow or signifier to show you can click to up/downvote.
Great job!
