Not so. I was weaned on black sabbath and deep purple, yes, crimson and all the good progressive band. Couldn't abide motown when that came, along and punk still makes me want to vomit.
BUT my kids were into Metallica, sepultura, rage against the machine, machine head etc. Loved it and I've got loads of their CDs although I still can't get on with chilli's and aerosmith. Later on the Scandinavian metal, fintroll, Moonsorrow etc. Still love and listen to Moonsorrow. So I'm still looking out for good stuff, it doesn't have to be the Beatles.
