Gotye sweeps primetime TV

If you haven't heard of Gotye, well, you probably have.

The 30-year-old Belgian-Australian musician's breakup anthem "Somebody That I Used to Know" was covered to death last week, first on "Glee" by Darris Criss and Matt Bomer then again as a duet between Elise Testone and Phil Phillips on "American Idol" and the artist himself is set to appear on "SNL" this weekend.

All the pre-publicity seems to be working out for him, as the highly-addictive tune is number one on iTunes, probably thanks to its primetime plugs.
