Here are the lyrics to most of Backstreet Boys Songs:

10,000 Promises
All I Have To Give
All I Have To Give (Conversation Mix)
Anywhere For You
As Long As You Love Me
Back To Your Heart
Boys Will Be Boys
By My Side
Christmas Time
Darlin'
Donde Quieros Yo Ire(Anywhere For You in Spanish)
Don't Leave Me
Don't Wanna Lose You Now
Don't Want You Back
Everybody (Backstreet's Back)
Everytime I Close My Eyes
Get Down (You're The One For Me)
Give Me Your Heart
Heaven In Your Eyes(as known as I Need You Tonight)
Hey Mr DJ (Keep Playin' This Song)
If I Don't Have You
If You Knew What I Knew
If You Stay
If You Want It To Be Good Girl(Get Yourself A Bad Boy)
I'll Be There For You
I'll Never Break Your Heart
I'll Never Find Someone Like You
I Need You Tonight
I Wanna Be With You
I Want It That Way (ver.1)
I Want It That Way (ver.2)
It's Gotta Be You
Just To Be Close To You
Larger Than Life
Lay Down Beside Me
Let's Have A Party
Like A Child
Missing You
My Heart Stays With You
Nobody But You
Non Puoi Lasciarmi Cosi (Quit Playing Games in Italian)
No One Else Comes Close
Nunca Te Hare Llorar (I'll Never Break Your Heart in Spanish)
Quit Playing Games (With My Heart)
Roll With It
Show Me The Meaning Of Being Lonely
Spanish Eyes
Set Adrift Of Memory Bliss
Tell Me That I'm Dreaming
That's The Way I Like It
That's What She Said
The One
The Perfect Fan
We've Got It Goin' On
Where Do We Go From Here
Who Do You Love
