^ PERFECT Debut-performance!
And the fans were screaming so loudly!
Ah, right, it was only about "MAMA" the song!
Further down in the Omona-post it says:
EXO-K and EXO-M’s mini-album, also titled ‘MAMA‘ and which consists of 6 tracks (including “MAMA”), will be released on the originally scheduled day, on April 9th.
So a little while longer, guys!
