I guess the "Round and Round" release has been canceled/postponed, because T-ara are repackaging "John Travolta Wanna Be" next week and it's not on the tracklist:
01. Roly-Poly in 코파카바나
02. Roly-Poly
03. 진짜 진짜 좋아해
04. yayaya (Remix ver.)
05. 왜 이러니 (Remix ver.)
06. Ma boo (Remix ver.)
07. 몰라요 (Remix ver.)
08. 괜찮아요 (Remix ver.)
