My favorite song of all time is Sister Ray by The Velvet Underground, being the last track on their second (and best) album White Light/White Heat. It's a bit hard to explain why I like it so much, but I'll try.
I love the instrumentation throughout the song, it seems like the band members are competing to see who can hit their instrument the hardest while Lou Reed provides the vocals and the drony guitar, and while the instrumentation constantly changes as the song goes on, the vocals remain mostly the same while changing some lyrics, the repetition of the vocals makes them seem not as weird by the end of it, also really fun to sing along because of the occasional call-and-response that happens between the vocals and the instruments.
Something else I like about the instrumentation is that a lot of the time it sounds like some kind of "domesticated" noise, which really makes it a unique listening experience.
Here's the link if anyone's interested:
