Hypebot (and others) have been suggesting for many months that one way to get consumers to actually pay for music is to think "value added". In other words, give them a reason to lay down $15-

$20 instead of grabbing it for free online or from a friend.
It now appears that those that are doing it (most notably Sony BMG and some indies) are being rewarded. Today Coolfer commented on a Hollywood Reporter piece that shows music DVD and DualDisc sales increasing even as standard CD sales continue to fall. "The days of a single format world are over," said one Sony BMG exec. Hypebot wholeheartedly agrees.
