My mom can tolerate most music... Though I think its because she is good at filtering it away!
My dad on the other hand likes trippy music, but I think he likes the less aggressive stuff whether it be Goa or psy... Remember one time I was listening to Shiva Chandra - Luna Spice he wanted me to put it on in the living room.
he was also the one to introduce me to electronic music when i was a kid, always playing Jean Michel Jarre and Pink Floyd... Remember he gave me a tape of J.M.J. - Magnetic Fields and I took it to my kindergarden? (børnehave) at the age of 4-5... the other kids though it was weird music, I loved it.
But my dad is a meditation freak so all music with chatting is a hit with him
