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
My first exposure to Pictures At An Exhibition was my parents had the Emerson Lake & Palmer version. I like the classical versions you posted better. https://www.youtube.com/watch?v=xWQct6D6HsM
