Not only was the Tupac Shakur Hologram a hit at the Coachella Music Festival, it also boosted sales of the late rapper's posthumous albums. Buoyed by his virtual performance, Tupac's 1998 album Greatest Hits returned to the Billboard 200 album chart for the first time since 2000.

The collection entered at No. 129 with 4,000 copies sold. Other albums by Tupac that saw a sales bump included his 1996 effort 'All Eyez on Me' (2,000 copies) and his 1995 LP 'Me Against the World' (1,000 units).

Elsewhere, the two songs from the virtual Tupac's Coachella performance, 'Hail Mary' and '2 of Amerikaz Most Wanted' (featuring Snoop Dogg), netted 13,000 and 9,000 downloads, respectively, last week. Meanwhile, his 1995 chart-topping hit 'California Love' (featuring Dr. Dre) garnered 11,000 downloads.

While the resurgence in Tupac's music is benefiting the late rapper's estate, some may look at it as exploiting the dead. Atlanta rapper Waka Flocka Flame is among many critics who wasn't feeling the Tupac hologram.

“I hated it,” he said. “That s--- wack. I don’t think they should be doing that [because] they getting paid off a dead man’s body. You gotta let that man rest in peace. He’s a great.”

Hopefully, Tupac's sales bump was sparked by a new generation of music fans interested in learning more about the late rap icon. If that's the case, then it's a win-win situation for the listeners and Tupac's enduring legacy.
