I think I came up with a non-insane-cost version of Doug's power. It's hinky, and would require full GM approval, but I think this works it out.
Ultra Power (Supers, pg 30)
(Always On [effects are dangerous; Mitigator {Non-Resonating Music}], Cosmic: No Die Roll Required, Extended Duration [x10], Magical, Nuisance Effect [Unpredictable], Reduced Fatigue Cost [14; not sure what Doug's FP total would be], Reduced Time [13], Reliable +10, Trigger [Common, Resonating Song]).
With Multiplicitive Modifiers, it comes out to 303 points. Not bad for a power that lets you do pretty much anything. There's also room for plenty more limitations on that sucker.
