How about “Young Lust” vs. “Great Gig in the Sky” by Floyd? Or pretty much any song from the Syd era.
I had someone try to convince me that Young Lust counted as progressive rock because Pink Floyd performed progressive rock and The Wall was a progressive rock album.
Not a persuasive argument, but a memorable attempt for sure.
“Teardrops on My Guitar” and “Blank Space.”
65daysofstatic - “retreat retreat” and “sister.” One is definitive post-rock, plus an uplifting anthem for the band. The other is a slow, foreboding ambient electronic piece. No shared instruments, themes, or genres between the two.
I listened to the No Man’s Sky soundtrack so many times, thanks for the rec!
Smash Mouth - Pet Names
Smash Mouth - Whole Lotta Love
Or basically anything from Fush Yu Mang compared to their later stuff.
Beach Boys: “Surfin USA” and “All I Wanna Do” (there are plenty of other examples too)
Beck - Devil’s Haircut and Heart Is A Drum
Get Dead - Kerouac’s teeth vs Disruption
Get dead just goes on all my playlists they have a song to fit most my vibes
