Filesharing-savvy CD promo strategy for Green Day

BoingBoing Matthew Hawn says, "The band Green Day is selling pre-printed CDRs with the artwork of their last 5 major-label albums. You can buy the pack for $7.99. The band is coyly suggesting that these are for people who buy music digitally but file-sharing fans should rejoice that their CD don't have to look home-made. Nice gesture from the band to their fans… and a clever marketing ploy by their label, Warner Bros." Link
