My personal favorite. I don't know why, but it's my favorite beat of any song I've ever heard. It's simple, but perfect. I don't even need the damn vocals lol.

EDIT to add my other Wu favorite.

Not going to lie I am insanely ignorant to Wutang...Except for 36 chambers I own none of their immense catalog...Im digging the guidance here...

You should make buying Only Built 4 Cuban Linx by Raekwon and Ironman and Supreme Clientele by Ghostface Killah. No one ever mentions No Said Date by Masta Killa but that is preety damn dope as well. Like Scruffy said, the first go round of albums are great, but I can even dig some of the stuff on U-God's solo album. A whole album of U-God can be tough to take all at once, but has some good guest spots to make it worth your while. Especially track 3 on that album, can't think of the song title. 

No real diss tracks that I know of, but on Supreme Clientele there's a diss towards 50 Cent but it's not a song, it's one of the spoken interlude type tracks up on there. They never really did diss tracks.

Also, GP WU and Killarmy put out some classic type Wu shit that was mostly done by the RZA and 4th disciple. Another must have is The Swarm CD. Not to be confused with The Sting, which kinda sucks, but The Swarm is one of their little known collaboration albums that is absolutely the shit. Buy it.

Sure does. Wu-Tang put out something original back in the day, and it's still the shit now.

Gravediggaz are the shit. I totally forgot about that album, good call man. Their second album The Pick, The Sickle and The Shovel was pretty damn good too, but it took me a little while to get into it. Not as good as 6 Feet Deep but still has some Gravediggaz classics on it, for sure. They had another album alfter The RZA and Prince Paul left the project called Nightmares in A Minor with just Frukwan the Gatekeeper and Poet. When Poet died of bone marrow cancer, Frukwan put out the fourth Gravediggaz album with just him on it, called 6 Feet Under, which was surprisingly not bad. Check those out sometime if you like the GRavediggaz and haven't heard those two, you'll probably like them as well.
