I could be chasing but my time will be wasted.
They got nothin＇ on you baby.
Nothin＇ on you baby.
They might say hi and I might say hey.
But you shouldn＇t worry about what they say.
Coz they got nothin＇ on you baby.
Nothin＇ on you baby.
I know you feel where I＇m coming from.
So baby regardless of the things in my past everything I＇ve done.
Cause you and I know it was just for fun,
I was on the carrousel I just spun around.
With no direction, no intentions
It all ended.
It＇s so much nonsense,
it＇s on my conscience
I＇m thinking ＂maybe I should get it out＂
And I don＇t wanna sound redundant
But I was wondering,
if there was something that you wanna know
But never mind that,
we should let it go
Coz we don＇t wanna be a T.V. episode
And all the bad thoughts,
just let em go, go, go
