I'm not sure what the effect should be exactly, besides amplifying the next song somehow minute-for-minute with how long he plays this one first ("For every minute I have to work, I get a minute of pay") Simply expanding his effect radius seems obvious (he can rock you from further away) but is usually not within the bounds of his effects, and even if it's good enough to generate a power, I don't think it has the touch to break the normal limit on powers. Maybe just making them more intense? It would require judging the alteration per-song, but that's nothing new for Doug
