歌手：98 Degrees 专辑：The Collection
98 Degrees - My Everything

The lonliness of nights alone
The search for strength to carry on
My ever hope has seemed to die
My eyes had no more tears to cry
Then like the sun shined from up above
You surrounded me with your endless love

You are my everything
Nothing your heart won't bring
My life is yours alone
The only love I've ever known
Your spirit pulls me through
When nothing else will do
Every night I pray
On bended knee
That you will always be
My everything

Now all my hopes and all my dreams are suddenly reality
You've opened up my love to feel
A kind of love that's truly real
A guiding light that'll never fade
There's not a thing inlife that I would ever trade
For the love you give it won't let go
I hope you'll always know
