求解歌曲once in a life time中文意思
觉得直译成生命中的一次好象少了什么似的,有朋友告我别总求解中文意思,或者译出来就不美了,可是还是想找一个合适的译文,

我的翻译：唯愿今生有一回
Once In A Lifetime
---------------------------------------------------------------
Everyday I pray...to help me through the day...
to make myself stronger...
and I pray...
So long I've waiting for my dreams to come to life
Believe that faith would make them come true
And when I close my eyes in my heart i knew that someone was..
gonna listen my prayers..somehow i knew
Beneath the stars at night I promise I would always try
And now i know it was worth the while
Although it's hard sometimes you know that my love is always on your side
You can make it happen just believe
Once in a life time Fly to the stars
There's no denying just believe in who you are
Once in your life time Let me take you there
Cause you dont have to feel all alone you know
I will be there
Through all the joy and pain my dreams wont fade they sill remain
Rainy days always come and go
But love is always there I know as long as you are here with me
That eventually you'll see u oh~
Once in a life time Fly to the stars
There's no denying just believe in who you are
Once in your life time Let me take you there
Cause you dont have to feel all alone you know
I will be there
Don't you ever let go or shed a tear
(No Baby No More Cry)
I'll be there so have no fear
(I will pray for you and me tonight)
When the moment's right
You'll know inside it's time
Inside you always knew
Dreams can come true
Once in a Lifetime
