Vocal Twins: Yea or Nay?

Have you ever heard someone talk or sing and thought you were listening to someone else until you looked?  That happened to me this week.

I was doing some work online when I heard Ro James "Permission" come on the radio.

I love the sound! Totally shocked me when I saw the artist's name because I thought for sure it was Jack Freeman, whose music I've been enjoying for a few years now.

Is it just me or do these two sound alike? What other recording artists sound alike to you? Has your sister ever called you on the phone or called your name from another room and you had to check to see if it was your mother?  If so, share this and tag them.
