Our music worlds really don't intersect.
Mozart will always have an audience, and he gets time on my turntable a few times a year. The Beatles will probably always have an audience. Pink Floyd, maybe.
Will any of the guys you listed still have an audience in 100 years? I don't know any of these artist. Listening to the links, some of it is ok. Some not. But it's a big world of music, and we all listen to what speaks to us.
