One unforeseen hazard of going to the gym regularly is the music. My gym is better than most, but it's still a lot of eurodisco, house and the stuff you'd hear on commercial radio. It works at the gym, but those songs tend to stick... which is why I've been humming songs like this one. I blame my amazing indoor walking instructor Louise, she uses it in her class.
It's Det snurrar i min skalle (= it's spinning in my head) by Swedish group Familjen.
I've always had a soft spot for electronic music, but I prefer VNV Nation. If I ever start listening to Swedish House Mafia it's time to get me to rock n roll-rehab.
