Pop was a no-no when I was going through school. Basically the "battlelines" were drawn between Rock (Sabbath, Zeppelin, Boston, Pink Floyd ect) and the Disco/pop crowd (Abba, Bee Gees, and a whole host of 'one hit' bands). There really was no middle ground, you were for one or the other which was sad because I'm sure many on each side liked some of the 'other' music.

Half of communication is listening. You can't listen with your mouth.
