Hi ott, what music do you play to your daughter? Do you teach her to separate good music from crap music in any way? How does she like your music?
I would never encourage her to categorise music as 'crap'. I'm more interested in helping her define her own taste than imposing my own upon her.
She likes my music and knows instantly when one of mine comes on but she also likes the Robin Hood song, The Wheels On The Bus, Cardiacs, Sparks, Desmond Dekker and Pendulum.
