Lyric discussion by sleeves 

Cover art for Bunker Hill lyrics by Red Hot Chili Peppers

i think the lyric is actually "it would feel so good, to be cool with you"

and also it sound more like "blood into the drain" which makes more sense as well

@sleeves It's definitely 'cool', not good. However I do think it might be 'it would FEEL so cool' instead of 'it would be so cool'.
