Little Mix's Peri explained to Artist Direct
why the girls close their DNA
album with this song about breaking out of the madhouse. "When we were writing that, we were thinking about how music takes you over and gets inside of you," she said. "It's so good that you can't help but move. It makes you go crazy when you hear that song. It turns a bit creepier and creepier. We had those effects over "Welcome to the madhouse". It ends the album well!"
