Rita Ora - For you, intro sounds like trance song
 

This new Rito Ora song: For you, is on the radio a lot these days and everytime the intro comes on i recognize it as some sort of older trance song or techno song but i can't remember where its from. I feel like its from some armin van buuren song but i could be completely wrong. Can anybody help me with this?

I am talking about the sort of strings that play in the first 15 seconds of the song.(Btw i cannot post a link yet since its my first post)

Yea, thanks for observing that, i noticed the same thing too.
