MGMT, Chiddy Bang and *THAT* keyboard riff

I just made a brief playlist for my iPod -- two songs at 8.2 minutes -- of a song and its sampled spawn.
1. The 2008 single "KIDS" by MGMT reached No. 16 in the U.K. (but didn't chart in the New York duo's native America).
2. CHIDDY BANG took the keyboard riff from "Kids" to construct "OPPOSITE OF ADULTS." That recently released single reached No. 12 in the U.K. (but hasn't charted yet in the Philadelphia duo's native America -- hmm... do you sense a trend here?).
The song might not be so original, but "Opposite of Adults" sports a highly original video.

Thanks to this two-song playlist, I am certain to have *that keyboard riff* stuck in my head all day. That's OK.
