Yesterday we shared with you former Fly to the Sky member Brian Joo's new song titled In My Head. This song is actually a cover of Jason Derulo's In My Head. Earlier today Brian performed this track for the first time on Mnet's M! Countdown and now he has released a MV teaser for the track. Can't wait for the full MV, the song is appropriately titled because it does get stuck in your head as it's very catchy. Thanks to AznSamMan for the tip.
