I don't think that this is a primary dynamic for music. Partly, but not really to fans. I don't think fans are extra hyped because something sold out. It helps, but I don't think that's a motivating factor.

Within the industry - I can see that. Producers, managers, booking, PR, etc everyone loves the bandwagon.

And a big artists not selling as they would is kind of negative news, but I don't think that has anything to do with people respond to the next album.
