They understand their key market, and exploit it for all it's worth. I think this is the lowest(in context) that they've gone to drive sales of their album.
It's probably because the album isn't what has been expected. If you read their faygoluvers and site updates, you can tell they were bracing the fans for a lot of negativity found on the album. There's no juggalo chant anthem, or really any song on here that won't put fear in grandma's heart if you bump it too loud.
They really reached with this album, from its track mapping, to topics, to beats.
