And stop listening to your headphones altogether. Make up the most annoying musical compilations you can think of. (I used to call them 'Stereo Wars') Play them for him. Constantly. Loudly. When he's sleeping (on two stereos, or on your computer AND your stereo).

That'll either drive him off, drive him insane, or convert him. Anything is better than this.
