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.
James Bond by Iggy Pop
It annoys the shit out of my wife so I’d just let it play, then I started actually liking it
Incidentally, she did the same thing to herself with Chinese Man’s “Get Up”
