2NE1 I Dont Care

The song was released as the second single on July 1, 2009, with promotions starting in early July. The song marked a change in the group's image, as "Fire" showcased a stronger, edgier image; in contrast, YG Entertainment CEO Yang Hyun Suk stated that "I Don't Care" would enable the group to display a softer, more feminine image.
An unplugged "reggae" version of the song was performed on SBS's Inki Gayo music show, signaling the end of promotions for the song. However, due to the remix's popularity, it was released to digital outlets on September 3, 2009.
