Baby One More Time by Britney Spears.

Oh baby, baby how was I supposed to know, if something wasnít right here
Oh baby, baby I shouldnít have let you go, and now youíre out of sight, yeah

Show me how you want it to be, tell me baby cause I need to know, because
My loneliness is killing me, (and I), I must confess I still believe, (still believe)
When Iím not with you I lose my mind, give me a sign, hit me baby one more time

Oh baby, baby the reason I breath is you, girl youíve got me blinded
Oh pretty baby thereís nothing that I wouldnít do, itís not the way I planned it

Show me how you want it to be, tell me baby cause I need to know, because
My loneliness is killing me, (and I), I must confess I still believe, (still believe)
When Iím not with you I lose my mind, give me a sign, hit me baby one more time

Oh Baby, baby, Oh Baby, baby
Oh Baby, baby, how was I supposed to know
Oh Baby, baby, I shouldnít have let you go

Now I must confess, that my loneliness, is killing me now, donít you know I still believe
That you will be here, give me a sign, hit me baby one more time

My loneliness is killing me, (and I), I must confess I still believe, (still believe)
When Iím not with you I lose my mind, give me a sign, hit me baby one more time
