Well I guess it depends on the personality of the dancer.
Some sing some doesnt.
I love to see dancers singing (ok opening closing mouth lol) at instrumental songs (special at chorus of songs of Oum Kalthum) this shows that they feel the song (ok I mean when they really feel it and not fake it lol)
