"I Don't Care" is a song by Finnish rock band Apocalyptica, the song was released in 2008 as the third and final single from their sixth album Worlds Collide and features Adam Gontier on lead vocals. The song reached No. 1 on the Billboard Mainstream Rock Tracks chart for one week and No. 2 on the Modern Rock Tracks chart where it spent a year in the top 20.

There are two recorded versions of the song. The first one (length 3:57) was released in 2007 in Europe. Adam Gontier wanted to re-record the song for the US and Canada release of "Worlds Collide" in 2008 and that version is 3:41. In this radio edit version of the song, some explicit content of the lyrics, including the chorus's second half, are replaced. The radio edit version is available only on the single and the US and Canadian edition of the album. In a February 2008 interview for Brave Words and Bloody Knuckles magazine Eicca Toppinen from Apocalyptica explains why there are two versions of the song: "Actually we've reworked the song. Adam [Gontier] originally recorded his vocals in the spring (of 2007) with our producer (Jacob Hellner), but Adam wasn't entirely happy with the result. So a couple of weeks ago, Adam went to the studio with (Three Days Grace producer) Howard Benson to record a new version of the song. It's really great. It will actually be on the US/Canadian edition."

"I Don't Care" was based upon the instrumental track "Love Song", written by Eicca Toppinen for the Black Ice movie soundtrack.

As far as the concept of the video goes, "It's going to be a bit freaky," says Eicca. "It'll be surrealistic in many ways, maybe a little bit in the spirit of Tim Burton. There's acrobats, strange-looking people doing strange things. It's going to be shot in an old house where nobody lives; it's a big mansion. It's really spooky. Of course, the director, Lisa Mann, is the only person who really knows at the moment, but it's exciting for us. She really wants to bring out the people inside the band. It feels completely different. It has a really special look."
