It has been a big week for Gotye's massive left field hit single "Somebody That I Used To Know." First it was performed early last week on Glee's return from spring hiatus. On American Idol the song was performed as a duet by contestants Phillip Phillips and Elise Testone. Then this past Saturday Gotye performed the song live with Kimbra on Saturday Night Live. Since the Glee performance "Somebody That I Used To Know" has been lodged at #1 on the iTunes chart. Early word is that sales this week have surged past the 500,000 mark. It is possible it could be enough to boost the song, currently #2, to #1 on the Billboard Hot 100. That would match its achievement on the alternative songs and rock songs charts as well as pop singles charts all over the world.
