Owl City Scores Hit w/Postal Service Knock Off

If ripping off the US Postal Service is a federal offense, what kinda penalty would be imposed on whomever did the same to Death Cab for Cutie frontman Ben Gibbard's electro-pop side project The Postal Service?

Well, none at all it seems: Owl City has reached Billboard's Hot 100 and the Top 5 of the iTunes charts with this twee TPS carbon copy called "Fireflies". Ugh. [h/t Idolator.]
