Leave it to SM to give us bop after bop with these boys, but something about NCT 127’s latest comeback reminded me of f(x)’s 4 walls and so I needed to hop on this mashup as soon as I heard it in my head. SAVE and 4 WALLS are bops, and I have nothing but love and respect for the groups who performed them and the writers and producers who made these songs. Hope you guys enjoy!

Songs used:
Save -    • NCT 127 X Amoeba Culture 'Save' MV  
4 Walls -    • f(x) 에프엑스 '4 Walls' MV
