Wikipedia says, "The phrase E ticket (or E ticket ride) refers to an unusually interesting, thrilling, or expensive experience. It derives from the admission ticket system used at the Disneyland and Magic Kingdom theme parks before 1982, where the E ticket (officially termed "E coupon") admitted the bearer to the newest, most advanced, and/or most popular rides and attractions."
So I say, thanks, Wikipedia, for explaining what the hell this song is supposed to mean:
You tell me that you've found a better way
And I tell you that it isn't fucking sane
Everything that I wanted has broke down
They all think that I'm just a fucking clown
But everybody's telling me I gotta move faster
Everybody's telling me that I'm a fucking bastard
All my dreams were just islands in the sky
