This week on 'SM Station' season 2, f(x)'s Luna will be releasing a duet version of her solo song "Free Somebody".

Luna will be singing her duet with the winner of 'SM Station 2's 'Battle Singer'. The 'Battle Singer' project was a project launched by 'SM Station', 'everysing', and Genie Music, to find a new star to collaborate in SM's ongoing weekly music release series. The winner of 'Battle Singer' is a student named Hye Da, currently studying applied music & arts at Kyung Hee University's graduate school.

Look forward to Luna x Hye Da's "Free Somebody" this February 9 at 6PM KST.
