Query: Great actress, not a great singer.

I think Jennifer Lopez is a talented actress and dancer, but I don't think she has much of a singing voice. The best song on her CD is "No Me Ames", and that's thanks to Marc Anthony. Her voice isn't anything special and she can't even hold a note for long. She should just stick to acting and save her singing for when she's in the shower.
