I have no problem with a band that plays its own music on YouTube, as long as the post originated from the band.. But YouTube take very little steps to monitor illegal uses of their service. Napster had the same problem.
All those bars pay an ASCAP fee. They have to if they use the space for performances and/or use recorded music in their establishment. Even if every band played their own original music, the bar still has to pay the flat rate fee for use of their space as a performance venue. There’s no copyright issue there. Showing a video of said performance on the Internet, however, is not covered by that fee. There’s a big difference.
I understand technological advances. But there’s an alarmingly large number of people who feel that since technology allows for these infringements, that its reallty harmless since the money is going to "big corporation." Unfortunately, it isn’t harmless. And it adversly affects the musicians and composers who create the music.
