Modern-day corporate radio sucks lizard shit. Their playlists are thinner than an Ethiopian's waistline - if it doesn't have a hint of being commercial, it has no prayer in hell of getting airplay.
That's what I love about my gig at a community radio station. So long as I follow the FCC guidelines, I can play whatever the hell I want, and I purposely try to stay away from stuff you can hear on any of these cookie-cutter stations. I know over the past few weeks, I've played both "Godzilla" and "See You In Black" from BOC, "Only" and "Indians" from Anthrax and I don't remember which Pantera song I played. (Guilty on the Slayer, though.) I've also dug out other groups that deserve airplay, like Wishbone Ash, UFO, Rainbow, Nazareth (other than "Hair Of The Dog")... lots of stuff that at least I think is cool. So, there is hope outside of ClearChannel's grasp.
Whiplash and MetalThrasher, I know you guys aren't terribly far from me. PM me, and I'll send you the link to the station, so you can listen to my show on streaming audio. (We're a small station, so the signal doesn't travel very far... except on the Internet, thank God.)
