In no particular order:
There are certainly more I would happily wear in a little sea shell around my neck like the witch in The Little Mermaid. I would take Traci Chapman’s voice if I didn’t have to sing depressing pseudo-folk music with it, or Whitney Houston’s voice pre drugs and Bobbie Brown. I go back and forth on Mary J. Blige. It might be more attitude than talent that I admire in her case. Not that she’s a bad singer.
It’s hard to tell if I’d want one of the single name performers voices (Rihanna, Ciara, them folks) since if I’m going to get into vocal larceny, I want some serious power, depth, vocal range, all that stuff. Considering that thought, I think Mariah Carey is on the top of the list. Because let’s face it, that voice is totally wasted on her.
