There's a new collaboration in town, this time featuring After School's Raina,�?uNo (former SPEED�member�Taewoon), DAYDAY (DMTN member, aka�David Kim) and Jakop (DMTN's Simon)!

The four are having a good time dancing along and moving to the beat with scantily clad ladies in their new risque MV "Allday Allnight"!

The track is described as a retro punk number with a groovy bass line and funky brass sounds. It's definitely an upbeat song with both amazing rap and vocals.

Double Kick Entertainment�of the producing team which includes ?uNo, DAYDAY and Jakop, composed the song with Raina in mind for the song! They must have known how sweet Raina's voice is, and how well she works in collaborations.

It's nice to see ?uNo and DAYDAY again after their run on 'SMTM4' as contestants Taewoon and David Kim. Same goes for Simon or aka Jakop, who has been busy focusing more on his producing work.�
