"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, then lead singer of Three Days Grace, on lead vocals. The song reached No. 1 on the Billboard Mainstream Rock Tracks chart for one week and No. 2 on the Alternative Songs chart where it spent a year in the top 20. Meaning Eicca Toppinen spoke about the song in an interview for Dutch metal webzine Zwaremetalen in 2007: "I wrote some of the lyrics to "I Don't Care." Max Martin wrote most of the lyrics, though.

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.
