Some is, some isn't. Always been that way. I'm pushing 57 and some of what I hear nowadays certainly doesn't get my motor running, but my 23-year-old son (who, by the way, is a crackin' guitar player in the Mark Knopfler vein) thinks it's fantastic. However, I listen to, for example, Eminem and I'm staggered by his lyrics. I can remember me old dad telling me around 1964 or 5 that The Beatles were a heap of rubbish and 'No one will remember them five years from now'. How wrong was he! It was an age thang!
Mooh's right, shite's in the ear of the beholder. One man's meat etc.
