Agree 100% with the OP. It's a message I have consistently given my kids as they were growing and I played them both kinds of music, country and western (kidding).
They were fed many shades of the spectrum from full on prog right through to jazz (not that I have much of that), and they took what they wanted from each genre. They now have actually quite divergent tastes which is interesting. The real point of "communion" has been the Graceland album.
