Eh, my girlfriend is generally supportive of me doing my music but I did try to introduce some of my music to her. And for that matter, it's black metal. She's kinda okay with it but I think she prefers symphonic and progressive metal. Wow. She is studying diploma in piano right now and she helps me out with my music theory.
But, my parents don't support my music and say it's "devil's music". Well, what can I do? Just continue headbanging. \m/
