What's the song name?

I'm not into the electronic music scene and never was, that's why I'm asking you.

I saw Tiesto's music clip on TV today but only few minutes in the beginning so I wondered what's song name since the song is so f*cking hot,

I YouTubed and found this:

It's called 'power mix' and this is exactly the beginning of what I've seen but what's the real song name without the 'mix' part?
