I think I must be missing something.
When I use the Music app, I can adjust the music volume with a slider at the top of the application's window. I use this to keep my music's volume much lower than I do my system sounds. However, if I open a music video in that application, the slider doesn't control the video's volume. The video window itself has a slider at the lower left, but that doesn't adjust the volume either.
How can I adjust a music video volume without adjusting the overall system volume?
