Jam of the Week: "Say Something" by A Great Big World & Christina Aguilera

 
The reigning Jam of the Week might seem mellow, but it's a jam no less. "Say Something" is the breakout hit of indie band A Great Big World. It's all about a reluctant break-up in which the singer begs his lover to "say something, I'm giving up on you."

The original version features just the band itself, but Christina Aguilera's presence on the re-release is what made the song such a big hit, and that's the version that wears the Jam of the Week crown.

One big question this song begs: is Christina's solo career over? Her last biggest hits, "Moves Like Jagger" and now this song, were with other bands, and neither Bionic or Lotus yielded any smashes. Just saying...
