It's all good. But to elaborate on the versions of Thug Luv:
Thug Luv OG, commonly mistakenly referred to as Thug Luv 3 by bootleggers and what not (since it was the third version to really hit the scene) includes two verses by Bizzy Bone, one verse by 2Pac and one verse by Sylk-E-Fine with the OG beat. Bizzy's first verse starts off with "Well look at the thugs that Mama gave up on..." and his second verse is from the retail release where he goes "Well it must be close to the Armageddon..."
Thug Luv II includes two verses by Bizzy Bone, one verse by Layzie Bone and one verse by 2Pac. If I remember correctly (since I was a very big fan of both artists at the time), this was the first version to leak on the internet in small parts in .wav files (since .mp3s were out but hadn't started circulating on as nearly as large of a scale just months later).
Thug Luv (retail version) is the version that appears on The Art of War. However, the first version of this that I got my hands on (probably around two weeks before The Art of War was released) was slightly different... maybe a line or two of Wish Bone's verse was different.
Feel free to correct any errors (if you really know what you are talking about if you were actually staying up-to-date in '96-'97, not just if you heard something from a friend who read online two months ago that blah blah blah), but I'm pretty certain that I'm pretty fucking accurate since I was watching the scene back then for both artists.
