I've had this song on repeat for practically the whole weekend.
It brings me back to the good ol' days .. late 90's / early 2000s when I first go into EDM. I'd listen to this kind of stuff for hours.
Anybody see this song played live?
And I think it's a reference to.. 👇

Hopefully we design strict ones. This is not ok. We should not tolerate any amount of it.
