If it's ever going to be released on DVD, The music will have to be redubbed with generic shit.
However, that's costly, difficult work, and it wouldn't be worth the money shelled out. WKRP is basically a cult show now, so it wouldn't make back the production costs and redubbing costs, like, say, Felicity would.
Oh, and by the way... WKRP comes to TV Land starting Friday night. It'll be on during their Kitschen every friday and saturday night.
2 episodes a week are better'n none.
