湖南衛視2017年全新音樂節目《歌手》第五場競演已播出，歌手排名再次迎來大洗牌。譚晶全新填詞《賽裡木湖的月光》風光奪冠，林憶蓮苦練手語雙「聲」演繹《克卜勒》，攻佔亞軍之位，張杰獻唱《默》躋身第三。而在上一場提名三甲的迪瑪希、獅子合唱團本周卻雙雙跳水，分列第六、第七。此外，本場新鮮亮相的林志炫與側田並列第四，側田由此挑戰成功，排名末位的趙雷則遭遇淘汰。
本周，獅子合唱團攜《It's my life》想冠軍再度發起衝擊，電音的低鼓，伺機而動的提琴，搖滾的吉他，主唱顆粒質感的嗓音與隊友磁性混響的低吼，一同渲染出這首狂野沸騰的硬派搖滾《It's My Life》！但此次獅子們卻未能續寫逆襲傳奇，遺憾排名第七。

This ain't a song
This ain't a song
For the broken hearted
Don't bend
Don't break
Don't back down
This ain't a song for the broken hearted
No silent prayer for the faith departed
I ain't gonna be just a face in the crowd
You're gonna hear my voice
When I shout it out loud
Loud
It's my life
It's my life
It's now or never
I ain't gonna live forever
I just want to live while I'm alive
It's my life
My heart is like an open highway
Like Frankie said
I did it my way
I just wanna live while I'm alive
It's my life
This is for the ones who stood their ground
For Tommy and Gina who never backed down
Tomorrow's getting harder make no mistake
Luck ain't even lucky
Got to make your own breaks
It's my life
It's now or never
I ain't gonna live forever
I just want to live while I'm alive
It's my life
My heart is like an open highway
Like Frankie said
I did it my way
I just wanna live while I'm alive
It's my life
Don't bend don't break baby don't back down
It's my life
It's now or never
I ain't gonna live forever
I just want to live while I'm alive
It's my life
My heart is like an open highway
Like Frankie said
I did it my way
I just wanna live while I'm alive
It's my life
It's now or never
I ain't gonna live forever
I just want to live while I'm alive
It's my life
My heart is like an open highway
Like Frankie said
I did it my way
I just wanna live while I'm alive
It's my life
