To add to Matt's ideas :-

LET THEM HAVE THEIR OWN TASTE AS THEY GROW UP!!!!!

Sorry for shouting, but when Dad talks all the way through Top Of The Pops, or the Pepsi Chart, going "This is complete ******.... In my day people could actually sing...." and so on, I think "Well, I think it's really good, so mind your own business."

Mind you, I do turn things like Limp Bizkit and Eminem up just to annoy him!!

There is ONE thing I can say in his defence :- He likes Eva Cassidy. Her album "Songbird" is currently No 1 in the UK album charts, so it's not ALL bad!
