请教各位：《怪物史瑞克》里的一首插曲

修改答案：
ALL STAR-----《怪物史瑞克 SHREK》插曲

Somebody once told me the world is gonna roll me
I ain´t the sharpest tool in the shed
She was looking kind of dumb with her finger and her thumb
In the shape of an "L" on her forehead
Well the years start coming and they don´t stop coming
Fed to the rules and I hit the ground running
Didn´t make sense not to live for fun
Your brain gets smart but your head gets dumb
So much to do so much to see
So what´s wrong with taking the back streets
You´ll never know if you don´t go
You´ll never shine if you don´t glow
Hey now you´re an All Star get your game on, go play
Hey now you´re a Rock Star get the show on get paid
And all that glitters is gold
Only shooting stars break the mold
It´s a cool place and they say it gets colder
You´re bundled up now but wait
