I love singing along with CDs while I'm driving or putzing around the house. It's great to be singing a baritone line with, for example, the Louvin Brothers, whose wonderful duets usually leave out a harmony part for me to jump on. Also, most singers are really average as far as pure vocal talent goes, but when you get 3 or 4 'average' singers together and they are singing harmony, it truly can be a great experience, more so, perhaps than singing individually. It just makes you feel good.   -btmp
