I'll comment on the ones I've heard:
Dogg Pound - Dogg Food
Nothing short of a classic, IMO. I can literally play this album from beginning to end, without skipping a song. When I speak of Kurupt, I speak of this as his prime. He lyrically comes nice on every single track. Daz doesn't slack off though. I've never been that big of a Daz fan, but I gotta admit, he definately steps up to the plate on this album. His production is nothing less than top notch and each beat fits each song to a T. Cop this and you won't regret it.
Nas - Stillmatic
There isn't anything that I can say that hasn't been said already. A classic in every since of the word.
Nas - God's Son
A tight album by Nas. In no way does it compare to Stillmatic, but it's a nice album. His production choice is skeptic, but then again, it wouldn't be Nas if it wasn't like that lol. IMO though, this album doesn't have much of a replay value. As nice as it is, it wears quickly. This album is good to have, but not necessarily an immediate pick-up.
*Note: See if you can get the version with the bonus disc, it has a nice freestyle where he tells a well put together story, another story (written though) and one more tight track.
Slim Thug - Already Platinum
Veerrry underated album. Me and my lil' bro was going to pick-up a CD together. I was getting Cassidy's I'm A Hustla, he chose Already Platinum. I tried to tell him, "Don't get it, it's going to be a waste of money." Naturally, he disagreed and copped it anyways. So when we exchanged albums to listen to, damn, I don't think I was ever more wrong in my life. This album was/ is ridiculous. Slim applies his lyrics to the beats on a great level. He can actually put songs together, too - something I thought he wouldn't be able to do. There are some cuts he could've left off, but all in all, it is a great album, especially for a rookie. Cop this most definately
Ludacris - Red Light District
About 2-3 songs on here that I like, and even the songs I like have no replay value. This shit sucks
Tha Eastsidaz - Dueces N Trayz
When I bought this album when it first came out, I don't know why I did. I must not have had anything else to spend my money on. It sucked so bad that I wasn't even mad after I listened to the album, mainly becuase I knew it would suck. Now once again, I don't know why I bought the album. My opinion: you can definately do with out this album.
