询问一首歌曲的歌词。


请问Katy Perry的歌曲《Roar》的歌词中有哪些部分？
歌曲《Roar》的部分歌词包括：

"I got the eye of the tiger, a fighter, dancing through the fire
'Cause I am a champion and you're gonna hear me roar
Louder, louder than a lion
'Cause I am a champion and you're gonna hear me roar"

以及

"I stood for nothing, so I fell for everything
You held me down, but I got up (hey!)
Already brushing off the dust
You hear my voice, you hear that sound
Like thunder, gonna shake the ground
You held me down, but I got up
Get ready 'cause I've had enough"
