Yoon Do Hyun, Reddy, G2, Inlayer, and S.M.ROOKIES' Johnny came together for a killer new 'SM Station' track entitled "Nightmare"!

Sure the hard-hitting sound and bold imagery may invoke nightmares, but ones you might actually enjoy because everything comes together so sweetly!  You'll be rocking out to this track, no doubt!

Check out the sick new song above!
