"Million Voices" is very familiar to club goers but, as yet, hasn't really crossed over.  Perhaps because the lyrics -- if you can call "eh eh eh eh eh, oh oh oh oh oh, ah ah ah ah ah, etc." lyrics -- are pretty minimal and hard to remember after you've spent the night partying.  Maybe the video will help, ie: "It's the one, you know, where the kids all find pieces of glass and put them in a circle in the woods and when they shine flashlights on it, smoke comes out and turns into the Northern Lights."  Yes, that one.  The song is by Swedish DJ/producer Otto Jettmann, aka Otto Knows.
