Music album was limited to a single copy and is the most expensive album ever (en.wikipedia.org)

> The winning bidder was Martin Shkreli, the CEO of Turing Pharmaceuticals, who paid an unspecified amount. In March 2018, following Shkreli's conviction for securities fraud, a federal court seized assets belonging to him, including Once Upon a Time in Shaolin. In July 2021, the US Department of Justice sold it to non-fungible token collectors PleasrDAO for $4 million to cover Shkreli's debts; PleasrDAO said they hoped to make it more widely accessible.

Martin Shkreli, the guy who jacked up Daraprim by 50x.

I think the most expensive album ever had two copies and it's the gold records on the Voyager spacecrafts. Wu-Tang is second behind that album. Also, Wu-Tang is Forever. So they've got that going for them too.
