If our calculations are correct, then Foster the People's stunningly catchy "Pumped Up Kicks" should be reaching song-of-the-summer status by late May. That gives it about three months to percolate through the blogosphere, into iPods, and onto a Gossip Girl episode. By then it'll already be playing in Mike's Apartment on repeat. Congratulations four guys that nobody knows yet, you're about to become the next MGMT (their chorus says "kids"!)—or is it Peter Bjorn and John (they whistle!).

How no one's picked up on these guys or this song on the music-saturated web is a great, great mystery. (Nylon TV apparently used the track to accompany footage of an Anna Sui fashion show, but we're happy to pretend that's not the case.) We found it on Hype Machine. Their sparse, official site has some more songs, but more songs are irrelevant when you've got yourself a hit like this. What looks like their first show ever is happening at the Viper Room in L.A., tomorrow night. Enjoy the intimate venues boys, they won't last long.
