Hey everyone,

Im trying to track a song which i keep hearing at work, i hear it in the background, the song is sung by a female vocalist and there is some piano section in the song. The only lyrics i have been able to hear are as follows but have had no luck online tracking the song down. Here are the lyrics im sure i've heard:-

But ive got time
Lots of things to do
Still have many things
But i dont have you
Every once in awhile
Just to keep you off my mind

Im sure the singer sing please or dreams a few times in the song.
Can anyone help me as i am getting desperate to find this song.
