I don't know about most people, but metal as genre is sooooooooooooo wide and diverse that it just keeps me interested. If I want to go slow there's something for me---- fast, uber melodic, jazzy, prog-ish, or madapakah fast and brooootal meron sa metal. Hell if I want the classical tones, I can also find it in metal...and wooopeeeee with distortion and that unbeatable drive and energy.
It has just enough stuff for me that nothing outside of it interests me anymore. Although I get impressed by the best players and songwriters from the other genres, they just don't trigger that pulse and that energy especially the intent and balls that metal has. Bayag pare! Bayag!
