A lot of my favorite music is from the 60s and 70s and they were pretty into the whole "super long, experimental" music trend. I've no doubt that drugs have something to do with it.

My favorite "long song" (at eight minutes and 32 seconds) is Don McLean's "American Pie".

If we're talking even longer, I'd have to go with Pink Floyd's "Shine On You Crazy Diamond" (Two songs, split at 12 minutes, 31 seconds and 13 minutes, 40 seconds). Pink Floyd was really, really big on long songs.
