Which are Cher's best songs?

I'm 16, and recently I have been liking a lot Cher. The songs I have from her are: Believe, Strong Enough, Song For The Lonely, I'll Never Stop Loving You, If I could Turn Back Time and the two which she sing in Burlesque. Could you please recommend me some other songs of her that you like :), thanks! and if you don't know who she is then don't bother to answer. :p
