One of the unfortunate things in this day and age is that Wal Mart has become the largest physical music shop in the U.S.. Though their commitment to the media is half assed due to sloppy shelves with no real rhyme or reason to how they're stocked. The product never matches the label cards. Which my account for why sales are down in music. You can't find what you're looking for when you're looking for it. This description also applies to KMART. Their spaces are just a total mess.
Then you have to factor in the dud practices that corporations delve into. WAL MART won't carry any cd with the Parental Advisory label that Jello Biafra refers to as the Tipper Sticker (which back in the day Al Gore was concerned more about young peoples' long term exposure to Ozzy Osbourne and Dead Kennedys lyrics than toxic atmospheric conditions). So artists need to keep their songs and artwork free of controversial imagery otherwise they can't be carried in the nation's largest music store.
Enter: GREEN DAY. A huge advertising budget (I suppose due to all the commercials and promotion it has been receiving) In a vast sea of shit being released available for download at I-tunes, virtually no proper print media or music entertainment channels a question comes into place, how do we make this new release an event. How do we keep "punk credibility" when our songs sound more and more like 38 Special ballads with a hint of more distortion? Take a jab at Wal Mart. Sam's homogeneous states of ineptitude.
Now don't get me wrong, if this helps get all the tweeny boppers to take their heads out of their asses and out of the MTV Reality delusion so many of these suckers are stuck in, great. This might be a slight at all the candy coating green washing, fair trade branded labour camps aren't going to stop the true nature of these oppressive regimes. So bravo to Green Day for finding something real to address. As for all my compadres who are upset that green day aren't punk as fuck anymore, who cares. You're not either.
