Wu-Tang Clan sold the single copy...

[Haxli]

...of its secret album for millions of dollars

"The auction house hasn't shared an exact number yet, but it confirmed that
the price was high enough to make Once Upon a Time in Shaolin the most
expensive single album ever sold. (It's breaking a record previously held by
Elvis Presley — Jack White bought a rare version of his first song ever for
$300,000 in January of this year.) The sale was actually made in May, but it
took months for the buyer and the Wu to sort out the contractual language
and protections surrounding the album. In any case, the sale price is high
enough to make you feel a little better about shelling out an extra 10 bucks to
hear the new Adele record."
