The boys of MBLAQ made their comeback last week after they unveiled their latest album and MV of their title track Y. Today, the boys made their second visit to Music Core since their comeback as they performed their latest hit track Y. By the way, is it just me or is their song getting addictive the more you hear it? Anyways, with their unique choreography, their performance was awesome. Check out their performance which more than makes up for their absence yesterday! http://www.youtube.com/watch?v=N-xeoUPIy0o
