I heard this song on the radio today, it's a woman singing it, she had almost an erika badu sound to her voice.

I think some of the lyrics are :
I'm going to hold on to all of my dreams, got to stay faithful to what I believe, I can only be me.

I did try to Google the artist by it kept coming back with a Stevie Wonder song which it is not.

Please advise if you know who else could sing this song!

Thanks for your help
