Old music. Do you like to listen to the classics?
YMCA is one of these well-known songs with a silly move. I encounter this kind of music everywhere, in Germany, in England, USA and even Costa Rican guys know these. Who knows if Lady Gaga will one day move up to one of those. Madonna definitely made it - she sang classics that cross decades.
Which songs do you listen to that you're maybe even ashamed of sometimes? The macarena is probably the most ridiculous song that people (mostly with a bit of alcohol) love to dance. At least English people do. We have a night called "Big Bad Cheese" - it took me a year to figure out that it's an ironic title commenting on the cheesy music they play there. The macarena is a weekly special. YMCA not so much, though I'd have loved to do the moves. I'm lucky though, because it's played quite often in Germany.
