That's one of most ignorant opinions I've ever seen expressed. Throughout history there have been composers and performers. Some performers spend years of study and practice just to be able to do justice to the music of composers. Some composers are also skilled musicians but many composers have spent successful careers writing music that they hope others will want to perform. That's the dream of a composer; to have everyone want to perform and record his or her music.

Or maybe you don't mean "composed" music. Maybe you mean "folk" music that is handed down through generations of musicians. What would happen to folk music if people limited their performances to compositions they'd personally written?

Wake up and smell the roses.
