I'm a fan of food metaphors to explain attitudes to music. Giving up pop music is like becoming a food snob or a diet freak. You become a grouch. By all means know what you like, but don't stop being social, you know?
In fact it pays to listen to pop. It's easy to assume pop is pap, but the opposite is often true. It is not just thrown together, but carefully crafted and clever, cutting edge art. The average musician can learn from studying it.
Of course I say this from the safety of the UK where pop actually evolves month to month, and dance music (EDM over the pond) has been mainstream since the late 80s.
