I listen to alot of country music, its all my wife listens to, its where all the good musicians are heading since talent is no longer needed in mainstream music anymore. just about every band I see live these days uses playback and some the singers are lip singing and fans still pack shows and cheer. They dont even hide it they bring their apple computers and set them up right on stage where you can see the tracks playing. The thing I see most is bands with no drums or no bass but while they are performing you hear those instruments.
What I find really odd is people arent complaining, if you arent interested in seeing musical talent or just a live performance in general then youre over paying for what you can get at home with good headphones
