Did Usher Rip Off a Homer Simpson Song from 2003?

The folks at Jackson, Mississippi’s Y101 Morning Showgram radio show noticed that R&B artist Usher’s 2010 song “OMG” sounds oddly like a Christmas carol Homer Simpson attempts to write at the beginning of the 2003 Simpsons episode “Dude, Where’s My Ranch?”, complete with the “wow, wow, wow.” Homage,  plagiarism, or coincidence?
