放在这里面还真不知道什么意思呢。

这句歌词是错误的，当然查不到啊
what's wrong, what's getting you down?
is it something i might have said?
you're walking around
with your head to the ground
and your eyes are watery red
i know you've been through tough times
kicked around, thrown to the ground
but you've always been the strong one
so don't tell me that nobody gets you'
cause i'm standing in your corner
knocking at your door
you don't have to be alone
just call my name
let me be an answer
'cause it hurts me to see you this way
i wanna ease your pain
help me understand
let me be your shelter, my friend
we share a bond, you and i, we belong
we're like coffee and morning train
you strip my defenses
i catch your pretens
