It's hard to find all the NiGHTS songs because I don't think even half the people uploading know about Bitter, Sweet, Spicy versions of stage themes. Like I try to type Nights soundtrack Spicy into Youtube and it's a HIGH QUALITY RIP of the Bear Cha Cha Cha from Bear in the Big Blue House.
I guess there are extended ones that blend them all, but that wasn't the point of the multiple stage soundtracks.

See, like this loops from Mild to Sweet to Bitter to Spicy.
