Hello everyone!

I need a help with a song I've heard. It is killing me from the inside :P
I'd say its an indie, indiepop song. There are male and female vocals in the song with some interesting music, even feeling like an oriental one.
I catched them singing: "I'll never let go" and "never let go" several times during the song. I also heard man telling "I heard it thousand times before" or something like that.
The problem is, I tried so hard to find it on google, but it always gets me to some classic ballad like bryan adams etc. It's not a classic, slow ballad song, Rhytm is following their singing very well.

I hope this helps. )
Pleasee tell me which one is it, thanks!!
