It was this band and from what I saw the video was partly of the band performing infront of an audience and it kept flashing back to this one girl who had kind of light brown or maybe reddish brown hair. The lead singer looks like Chester Bennington (lead singer) from Linkin Park with short dark hair... in my opinion lol... I don't know if that helps. Kind of a pop sound... no hardcore yelling in it... great singer. Real catchy tune... almost sounds like maroon 5....

wow... this is kinda confusing lol.
