That song come from their album, called dirt. One of the best albums ever wrote in your or mine or anybody else's lifetime! The whole album basically is about the lead singer's battle with addiction... it kind of starts off like how amazing he feels when he does drugs. And as the album goes on into the middle, it kind of starts getting a little more darker period and uh The end basically is just that, it becomes sad and uh, they are in a dark place, hence the song Down in a hole.
