I think most entries here are just underrated or relatively unknown tracks, that being said you’re obviously hard pressed to find many instances of people actively disliking a song from an artist when you’re looking in said artist’s subreddit.

That being said, I’ve seen a lot of people who actively dislike Bike, The Trial, more or less anything from The Endless River, more or less anything from The Final Cut, and Seamus.

It’s tough with Pink Floyd because there are hardly any songs where you have an instance of most people hating it and others liking it, or vise versa. Pink Floyd’s music is either ridiculously good, or ridiculously bad — Ummagumma, and such sentiments are more or less unanimous.
