I am GUESSING that any potential ROI would accrue so slowly as to make the $1.5M price tag just a smidge on the pricey side. However, perhaps somebody like Mark Cuban doesn't want to pay royalties for playing "Cotton Eye Joe" anymore, and the obvious alternative of simply not playing the song won't come to them until after they've cut the cheque. ;-)
Me, I would rather have sprung for some shares of David Bowie back when HE was selling.
