Yeah my dad was the same , when I was in my early teens I`d listen to metal but by the time I hit 16 I became bored of it & branched out, but for some reason my dad kept on thinking I was into metal , even though I`d show him new stuff I got like The Stones or The Who.He`d come home with Smiths , Roxy Music , REM & Elvis Costello & i`d say to him 'I dunno why you got those for I already have them'.
