The Insane Clown Posse have much more merit than most people are willing to give them. Their cult-like fans can be annoying. But then again, so can hipper-than-thou, Sonic Youth worshipping pricks.
If anyone wants to give the group an honest shot, anything from Intelligence & Violence to Ringmaster is golden. With Hell's Pit being their best post-Ringmaster album. I'd recommend The Mutilation Mix (greatest hits that were never hits) for anyone looking for a mix of high quality ICP songs.
