Not sure what your talkin about but Tupac didnt sell 25,000 albums in 1991, in fact his first 3 albums didnt sell a combined 10million....All Eyes on Me sold well before he died, and was his first pop success, but it tripled sales after he was gundowned and murdered in Sept. of 96.......it wasnt til after he died that his albums sold....
His 8 albums combined have sold a total of 26.5million copies, which made him the most successful rapper of all time(until recently when JayZ out sold him, with his last album totals)...
