HIP-HOP Wu-Tang Clan Disses Martin Shkreli on New Song 'Lesson Learn'd': Listen

The contentious feud between Wu-Tang Clan and "pharma bro" Martin Shkreli heated up on Friday (Sept. 22), when the prestigious rap group thrashed the pharmaceutical boss on their latest offering "Lesson Learn'd."

Inspectah Deck delivers the massive haymaker, rapping: “Hater/ Wouldn’t last a day in my shoes/ You know very well/ Bet he swell/ You can tell he jeal’/ My price hikin’ like the pills Martin Shkreli sell." In 2015, Shkreli became notorious for spiking the price of Daraprim from $13 to $750 per pill. Daraprim is medication used to treat AIDS patients.

Last year, Ghostface Killah slashed Shkreli in a scathing 12-minute interview, in which he referred to him as "the man with the 12-year-old body" and "PeeWee Shkreli."

Earlier this month, Shkreli opted to put the $2 million album, Once Upon a Time in Shaolin, up for sale on eBay. Last week, rumors surfaced regarding the legitimacy of the album. Domingo Neris, manager of U-God, debunked the entire project: "It's not an authorized Wu-Tang Clan album. It never was," he said.
