Cover art for Bleed lyrics by Animal Collective

when i first heard this song, i felt really bad for some reason. like i had done something to disappoint someone. then i heard noah's background vocal towards the end. i was asking myself what this feeling was from, when noah started repeating, "that's from this weed." i felt dumb for being high. just one alternate interp.

pretty sure noah is just repeating "Then I must bleed" ...

I guess you could say it's "that's from this weed"

but that would just demean their music.

"but that would just demean their music." - How so? I mean, I don't believe that is what he is saying and I think "octopuscollective" misheard but in the context of it meaning something to them for that specific song why would it be demeaning toward their music?

You're right.. it wouldn't demean their music. It would demean their intelligence and how they feel.
