why is sleep such an underrated song?

i saw this video a while ago talking about my chemical romances least streamed/listened 2 songs and sleep was like #3 or smth, and then it hit me, y is it so low?????

the black parade (tbp) is mcrs most sold album and by far their most popular album, so y would sleep b so low ?? i get popular albums can have unpopular songs but tbp ??????? TBP ???? A UNPOPULAR OFF TBP ???? 

Its not musically bad from any stand AT ALL (its a beautiful amalgamation) sure its no welcome to the black parade or teenagers but i just cannot comprehend y its SO UNPOPULAR?  

sleep is so beautiful and actlly 1 of the most underrated sngs on the album
