First is a British indie-rock-two-man-band. I didn't know which song to chose, Wonderful Life or Better than Love but I liked the video more for Wonderful Life.
Next is a bit older band, Gorillaz. I haven't been their hugest fan, but this song is really, really nice. Just sit back and relax.
Oh yeah, we need some dubstep too. Preferably by Rusko.
