They play them at my work all the time and I currently have them stuck in my head. Don't work for another week and who knows if they'll play the same station.
Song #1: Singer sounds like Kings of Leon, the chorus is just whistling, really up beat and catchy, has some lyrics about "You and I" and "change the world".
Song #2: Sounds like deadmau5 in the background with female singer (not medina... does remind me of the song You&I though), sounds kinda like she's singing "I'm a believerrrr" in the chorus.
Both new songs.
I will be slave for person(s) who finds said song(s).
