Controversy, controvery… two lines of Usher/Will I Am’s smasherino “OMG” are very similar to two lines of a Homer Simpson satire off the Simpsons. The song is a Homer christmas carol from episode 14 but it might be worth noting that the song is somewhat generic in both cases and hardly melodic works of artistry (one doesn’t need to, the other makes up for it with rhymic loops up the ying yang).
Still, fun stuff, take a look.
