Children, children, let's not have this degenerate into a pie-flinging contest or anything equally nasty.
Here's something to chew on: Disney World has the good fortune of being affiliated with one of the most comprehensive entertainment empires on the planet; the folks who handle musical programming throughout the parks basically only have to decide WHICH award-winning/beloved/universally recognized Disney tune to play at any given time.
The folks at Six Flags aren't so fortunate; yes, they have the affiliation with Warner Bros., but you can only play the Looney Tunes/Superman/Batman themes so many times, so the people who handle programming have to work a bit harder. If they want to play Disney tunes which the vast majority of their guests will recognize and enjoy, then why should they be criticized, provided they provide the requisite royalties to Eisner and Co.? Six Flags simply doesn't have a behemoth movie and music affiliate to fall back on, unlike the Disney folks, so give them credit for doing what they do. Not everyone in the country has the time or money to take a trip to Florida and California, so why criticize someone for trying to partially fill the gap. For those of us who love Disney World, Six Flags won't ever be the same, but to dismiss them completely seems rather narrow-minded.
