That said, please enjoy this video which has nothing to do with what was written above.Some guy on the interwebs wrote: I believe this song, though very good, hides a darker meaning within its lyrics. I listened to it while reading Mein Kampf and it just sorted falling together as a song about the Nazi Empire. Think of it from Germany's perspective:
Theres only two types of people in the world,
The ones that entertain, and the ones that observe,
Well baby I'm a put-on-a-show kinda girl,
Don't like the backseat, gotta be first.
In the beginning of the war, Germany was very angry about the way the rest of the world was treating it. Instead of sitting back, they became a "put-on-a-show kinda girl" and launched what would soon be known as the most deadly war of human history. "don't take the back seat, gotta be first" could be interpreted as making the first move and invading Poland in 1939.
I'm like the ring leader, I call the shots,
I'm like a firecracker, I make it hot,
Until around 1943, Germany called all of the shots. She was winning. "Like a firecracker" means "I'm dangerous", and "I make it hot" alludes to the Holocaust and the corpses of learning camp-goers being cremated when they refused to take showers.
There's only two types of guys out there,
Ones that can hang with me,
And ones that're scared,
So baby I hope that you came prepared,
I run a tight ship,
So beware.
This would be Germany's betrayal of the Soviet Union. When she saw that the Communists were weak and fallible, she cut them loose.
All eyes on me, in the centre of the ring, just like a circus,
Britney Spears is very proud of Germany's "heroic" actions.
It goes on to several more stanzas of pro-Nazi lyrics, but I think you get the jist of it. This song is about Britney Spears' admiration of the Nazis' "circus"-like spectacle.
Nice mood
