"...all music evolves..."

It does, does it? I suspect that this is an example of the 'progress myth' (things have a tendency to get better). Unfortunately, 'it ain't necessarily so'(to coin a phrase).

As far as I can see, what happens in music is that, at certain times, certain forms tend to dominate. Think of the dominance of the Western Classical form over all other forms of music on world concert stages. And think of how the the Rock form has come to dominate popular music. I suppose that some will argue that this is evolution at work - but there is no law which says that a particular individual has to like it.
