Former Fly To The Sky member Brian Joo kicked off the week with the release of his new digital single. After two nights of hypnotizing fans, he returned to the stage and performed his track In My Head on Music Core. In My Head is originally a song by American singer Jason Derulo. Much like last year's Wheesung-David Craig international cover collaboration of�Insomnia, Brian borrowed Derulo's track and put his own k-pop spin to it. Both tracks are definitely good and highly addictive but which do you prefer? Watch as Brian gets in your head with his performance. http://www.youtube.com/watch?v=lQcQ-UYeVos
