And I think it would be naive and idealistic to think that the composer/songwriter/musician/performers don't have a roll in selling the music. Do I want to go to a concert where a computer is rolled out on stage and I hear amazing music, or do I want to see a performance with lighting and a performer working the crowd? The performance and the personalities of the performers are as much a part of the musical experience as just hearing sounds in headphones, in my opinion.
