My mum likes some tracks, for example Ticon - We Are The Mammoth Hunters. 
If she hadn't grown up in the middle of nowhere, I think she had been a hippie. She likes older Led Zeppelin, Bob Dylan, Beatles and other pop / rock from that era. So she has a good taste I guess. 
  
I would say my dad doesn't like music at all, though he sometimes listens to finnish "iskelmä"  :ph34r:
