well, i dont know if its just me, but I aint THAT fascinated of the idea yet because somehow, I dont know if it would be so good for us to have a whole history of all of Pacs recording sessions becauze if he had it, than I guess most of our suprises about new released tracks would be gone, a lot of the excitement over a few new tracks would be gone cauze we would already all know about these songs, it would give us somehow a feeling of unnecessary omniscience which, in this case, I doubt is recommendable...So I cant really support the idea, I do admit it would be hella interesting to establish sth like dis, and I was thinking bout sth like dis myself alraedy long time ago (and yeah it does seem to give one a cool overview bout Pac's work), but as I sad, I dont know if we would have THAT much of an advantage of it..I mean the tracks will be released anyway some day I guess, PLUS, the information who was originally on the beats and the mic is usually delivered inside an album's booklet rite,so we WILL get this info anyway...so why not better restraining from such a chronological history? It may be different in 10 years or so, but for now, I rather disapprove of it.
