And if you look at what is happening on Bandcamp or Soundcloud or YouTube or wherever else young people are trying new things you see a tremendous heterogeneity of inspiration and not a lot of concern for where the sound fits in.
The parallel trend of course is the power migration from labels and producers to artists, and these are intrinsically related. The artist wants to experiment and find their own path, the label is always trying to replicate success (to radically oversimplify on both counts). Labels have a role to play in supporting artists, but the power dynamic is different when the artist brings the audience they've been building independently for years.
The direct connection between artist and audience shows how much more open to new ideas we can all be. It is the same receptivity that powered the integration Dylan describes taking place in the 1950s, and I think its great.
