I remember the 'Chart Show' every 4 weeks would have a rock and metal chart and that's where a lot of my now favourite bands were seen by myself for the first time
Nine Inch Nails - Sin for example.
I was so happy when my mum and dad got Sky TV and I started watching Headbanger's Ball every Sunday night at 11pm. Pretty much blew my metal horizons wide open then, I'd previously only been into Maiden, Metallica, Bon Jovi and GnR.
