Query: This is the one that did it.

So, this is the album that made me cross over to a person who buys hip hop. Mainstream appeal this definitely has, because even though I was familiar with alot of very intelligent hip hop I never actually went and bought hip hop CDs. But I couldn't pass on this one after listening to it. Of course, then I went and bought DangerDoom's Mouse and the Mask and now I think I'm on that proverbial slippery slope. But it's been fun so far.
