Short of drugs, I find music to be one of the most effective ways of inducing an emotional state on demand. If you want to hype yourself up, get that adrenaline flowing, what's your go-to song?
For me, it's definitely DJ Mehdi - Signatune (Thomas Bangalter edit). Hard-hitting French House. It's repetitive and brutal, and not at all what I would choose for a cozy, relaxed listening experience. But god damn if it doesn't get the adrenaline flowing.
