Mine is Sympathy For The Devil Song by The Rolling Stones
I could not take the background singers and it would enrage me!
hoo hooo hoo hooo hoo hooo for 6 solid minutes!.
I studied the song and the story behind it and became at piece with it eventually.
I just heard it on a YouTube channel and realized I like it now.
When I was first introduced to Pink Floyd by my father, the song he played was “Shine On You Crazy Diamond”.
Younger me had a bias against really long tracks, this went on for like 7 minutes, most of it was just instrumental with no lyrics until about minute 4.
But after a few years it really, and I mean REALLY grew on me, and I started to appreciate the hard rock genre a lot more for it’s slow but eventually anthemic build-up, and nowadays, it makes up a sixth of what I listen to nowadays.
I also didn’t like Bob Marley back in the day, but now I kinda vibe with that guy’s tunes.
