H&M store in Kensington Highstreet, London.

At 1.30 p.m. on the 21st of November 2011 I heard the best song I had ever heard. I was in the H&M store in Kensington Highstreet, London. There were no lyrics at all, baybe just electronic male vocal voices, it was a very electronic instrumental song. It had sounds typical to tub-step, nut the rythm wasn't quite tub-step rythm, in my opinion. The song was about four songs prior to DJ David Guetta's Titanium. I asked the store staff, but they didn't know the name of this song and told me that it is almost impossible to find it out. Can someone please help me?

And I also would like to know the name of the song with chorus lyrics "and it feels like...". The singer was probably male, but his voice was quite high. I also heard it on the 21st of November 2011 in the H&M store in Kensington Highstreet, London.

Not sure about the first song but the 2nd one is 'life is life' by Noah and the whale.
