get the whole collection. i think the first 3 were great, vol. 3 was kinda tame for jay-z, he picked it back up with dynasty and bp1, bp2 was underated but still would've fared better as 1 disc (make it yourself...don't get bp 2.1), black album was classic, and even the linkin park collabo is fun to listen to. the streets is watching sdtk has a few jay-z songs on there. i don't know about the 2 r. kelly collabo cds...i haven't heard 'em and until i have a reason to get them, i won't. but def pick up all his solos
