Here are a few to get things started:
Don Henley’s The Boys of Summer as an 80s synth tune
Bossa nova version of Crowded House’s Don’t Dream It’s Over
Reggae-ish version of Aretha Franklin’s Respect
A capella men’s ensemble version of Lady Gaga’s Bad Romance
I hadn’t but I’m adding to my playlists! I first got really into music via prog rock so this type of high-concept silliness is well-aligned with my preferences :P
