Query: There's a reason why these songs were unreleased...

Pac would record extra songs to vent his frustrations and get whatever he had off his chest. He never meant for these recordings to be released as he didn't see them as his "A" material. His mother is continuing to explot her son's considerable name at the expense of the quality of the music. Pairing him up with ppl who aren't good enuff to tie his shoes, let alone rap w/ him is a shame and a disgrace. These albums showcase the greed of Afeni Shakur, not the talent of her son.
