It topped the platform's chart, with four of the group's other songs tracking in the top 100, making 2NE1 the group with the most top-100 songs on Bugs in 2009. The song was ranked number one on Cyworld's 2009 year-end popularity chart in January 2010, the third consecutive track by a YG group to top the annual list. Although group members recorded and released solo material throughout late 2009, 2NE1 performed a reggae version of "I Don't Care" on Inkigayo in September; the reggae version became popular and was released as a digital single on September 3. Buoyed by the singles' success, sales of 2NE1 reached 120,000 units by the following year. 2NE1 performed at the sixth Asia Song Festival in 2009, representing Korea with three other groups and receiving the Asian Newcomer Award. In February 2010, the group released "Try to Follow Me" digitally to promote the Samsung Corby cellphone, with no previous announcement. The song peaked at number one on the Gaon Digital Chart. 2NE1 traveled to Los Angeles and London in mid-2010 to record English-language songs for an American debut album with music producer Will.i.am of the Black Eyed Peas, recording 10 songs in their initial sessions. The group released its first full-length album, To Anyone, on September 9. It debuted at number seven on the Billboard World Album Chart and amassed 120,000 preorders before its release. Several of To Anyone twelve tracks were released as singles, and the top-three hits "Clap Your Hands", "Can't Nobody", and "Go Away" were released with the album. 2NE1 was the first group in K-pop history to have three singles from one album top different music program charts, and was the first artist to top the Inkigayo chart for four consecutive weeks. The Halloween-themed music video for the fourth single from To Anyone, "It Hurts (Slow)", was released on October 31.
