Even better, the song in dispute is called "Spank":
The district court’s construction of § 411(a) was too narrow. Harrick Music registered a claim to copyright in the “Spank” composition, specifically identifying Smith as the composer and informing the Copyright Office the work was not made for hire. Nothing in § 411(a) indicates that a composer who has agreed to assign his legal interest in a composition, along with the right to register it, in exchange for royalties, may not rely on the registration his assignee files. Where a publisher has registered a claim to copyright in a work not made for hire, we conclude the beneficial owner has statutory standing to sue for infringement.As the song goes, "spank one more time"!
