介绍一首歌词是鼓励人上进的流行英文歌

本人很喜欢的一首，励志又有力量的女声roar-katy perry
部分歌词：
I got the eye of the tiger, the fire, dancing through the fire
我有老虎的眼睛，矍烁地穿透火光
Cause I am a champion and you’re gonna hear me roar
我就是冠军，听听我的咆哮
Louder, louder than a lion
大声，比狮子更大声
Cause I am a champion and you’re gonna hear me roar
因为我是冠军，听我咆哮
Oh oh oh oh oh oh
You’re gonna hear me roar
你会听到我的声音

Now I’m floating like a butterfly
现在化茧成蝶
Stinging like a bee I earned my stripes
成长得刻骨铭心
I went from zero, to my own hero
从零开始，终有所成
You held me down, but I got up
摆脱你的牵连
Already brushing off the dust
掸去灰尘
