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.
Paul McCartney - Wonderful Christmastime I used to hate it when I was little, now whenever I hear it I can’t help but smile because it brings back so many great memories!
Beautiful Life by Ace of Base
Basically the entire eurodance genre, when I grew up in the 90s/00s I absolutely hated the genre, it was just mindless annoyance to me, I enjoyed classic rock, but tastes change, and now half of my phone’s music library consists of eurodance, Aqua, Alcazar, Caramell, Dr. Bombay, Erasure, Fast Food Rockers, Gina G, Ian Van Dahl, Infernal, Las Ketchup, Los Del Rio, Me & My, Milk Inc, Mr President, Captain Jack, Nakaromi, O-Zone, Sunstroke Project, Paradisio, Rednex, Sash!, Solid Base, Sophie Ellis-Bextor, Sqeezer, Steps, A Touch of Class, Toy-Box, Vengaboys and Whigfield are all artists I either found or would have found increadibly annoying back then, now all of these are on my phone
You seem to be missing 2 Unlimited and Ace of Base.
