It's Showtime!
OHHHH YES!
WELCOME, BEAUTIES...
... TO TODAY'S QUIZ SHOW!!!
It's Showtime! Is the 49th track in the UNDERTALE Soundtrack. It plays after Mettaton bursts through the wall in the Lab and announces his surprise quiz show, as well as during the cooking segment that he hosts. It also plays during the Mettaton Ending, at 95% speed. A faster, shorter version of this song titled mus_tv plays on the TV in Papyrus and Sans's house.
Segments of Death by Glamour, Live Report, and Death Report share a melody with this track.
