EXO broke the one million mark in sales last year with their first album XOXO and the overwhelming success of \"Wolf\" and \"Growl.\" This year they're separating back into their EXO-K and EXO-M subunits to release their highly anticipated second mini-album Overdose in Korean and Chinese! Recorded in both EXO and subunit versions, the addictive title song is an urban R&B hip-hop dance number by Kenzie and The Underdogs. EXO-K's second mini-album features six tracks of various genres including the Korean versions of \"Moonlight,\" Thunder and Run.
