It seems that all the crazy good stuff is exclusive to the 360. Burn, Guitar's SUCK, Nihilanth, the chaterope songs.
I already have Death Quota for Purification and it's a really fun and varied chart. Also anymore songs that are like Buster Voodoo which are kind of easy but very fun at the same time.
It really sucks that there is no preview option for PS3 users.
