This song is In The Air
One of my top favorite trance songs, whenever this plays I can't skip it. The rhythm and pulse knocks me out cold. I had the fortune to have kept this on my phone while I was touring Italy a bit by train, as you can imagine I slept like a log, but with the most awesome and lucid dreams I've had in a while. I'm still not sure why this particular track has this power over me, but I think it has something to do with the pulsing beat in the background.
Besides it's disturbingly direct power over my ability to stay awake this track has been out for quite a while. If you're looking to get an especially good deal out of a bunch of trance and electro songs, check out Laptop Symphony on iTunes or Amazon. You won't regret it.
