The government wants to seize Martin Shkreli's one-of-a-kind Wu-Tang Clan album.

The recording that Shkreli has boasted he bought for $2million - the only copy in existence - is on a list of assets that prosecutors argue the jailed former pharmaceutical CEO should forfeit after his conviction earlier this year in a securities fraud scheme involving two failed hedge funds.

In a letter filed this week in Brooklyn federal court, prosecutors told a judge that Shkreli is on the hook for $7.3 million.

This week, the federal government filed to seize $7.3million from 'pharma bro' Martin Shkreli in relation to his fraud conviction (pictured above in August)

In addition to $5million from a brokerage account, they also want to seize some of his possessions including two unreleased rap albums - Wu Tang Clan's Once Upon a Time in Shaolin (left) and Lil Wayne's Tha Carter V (right)

The 34-year-old 'should be held financially responsible and forfeit this amount as it was obtained by him as a result of the fraud,' the letter says.

Along with the Wu-Tang Clan 'Once Upon a Time in Shaolin' album, prosecutors say Shkreli should give up $5 million in cash in a brokerage account, his interest in Turing Pharmaceuticals and other valuables including a Picasso painting, an Enigma machine and another unreleased recording that he claims he owns, 'Tha Carter V' by Lil Wayne.

Defense attorney Ben Brafman said on Friday that Shkreli would fight the forfeiture.

'Our position is clear: None of the investors lost any money and Martin did not personally benefit from any of the counts of conviction,' Brafman said in a statement. 'Accordingly, forfeiture of any assets is not an appropriate remedy.'

Shkreli made national headlines in 2015, when his phmarceuticals company jacked up the price of AIDs medication Daraprim to $750 a pill

The boyish Shkreli - also known as the 'Pharma Bro' - is best known for jacking up the price of the life-saving AIDs medication Daraprim and for his snide persona.

A judge revoked Shkreli's $5 million bail and threw him behind bars in September after he offered a $5,000 bounty on Facebook for a strand of Hillary Clinton's hair.

He's due back in court for sentencing early next year, when the forfeiture demand will be decided.
