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
EDIT: This has been great, everyone. Thank you all for the terrific links and for introducing me to a number of artists I wouldn’t have heard of otherwise. Seriously, the online rabbit-holes have been thoroughly enjoyable–even if I stayed up a bit too late a number of times.
Worth it.
You’re welcome! And have you heard of Servotron? https://www.youtube.com/watch?v=4gS4nzSWmCs
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
