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.
Love them! This song in particular is pretty meaningful for me. My dad has always had a bit of a narrow conception of what “good” music is, so while we could bond over stuff he liked, he’s never been particularly receptive when I’ve shown him new stuff. John Prine was his favourite artist, though, and this cover got him to open up a little.
