I remember running into an old college friend in Fry's, a year or so after graduating, and arguing over Britney Spears' voice. She said that although Britney wasn't her favorite person to watch, she loved that her voice stood out from most singers and was unusual. I often think back to that day and honor her opinion, but enjoy my own interpretation of that. I am easily bothered by singing voices and wince when someone is too whiney or uses a lot of vibrato (that shaky sound). Right now I am smitten with two voices. Two voices I enjoy in pop music, but two voices I especially like to hear acoustically. Is this your cup of tea? Maybe not, but for me I am in auditory bliss right now.
