K-pop quartet 2NE1’s farewell song “Goodbye” has topped iTunes charts in eight Southeast Asian countries, with its music video surpassing 4.5 million views as of Sunday.

The song, a ballad bidding goodbye to the group’s fans, ranked first on the iTunes charts of Hong Kong, Singapore, Taiwan, Thailand, Vietnam, Malaysia, Cambodia and the Philippines, upon its release Saturday.

The song’s lyrics, co-written by 2NE1’s leader CL and Oh Hyuk of Hyuk Oh Band, expresses wistfulness at the breakup of the group, which debuted in 2009.

The songs were composed by two-time Grammy nominee Rook Monroe and producer J Gramm.

“Goodbye” is officially the last single of 2NE1.

When 2NE1’s youngest member Minzy left the group in April last year, YG Entertainment announced that 2NE1 would continue as a three-member group. In November, however, the entertainment agency announced the group’s disbandment.
