For many reasons, I do not hold at all by R’ Aviner. However, note the following:
Those of us who know the morals of the entertainment industry know that most everyone involved does NOT fall into the above category. And that includes classical musicians as well – take an orchestra of 10 people and believe me, you have 1-3 MZ’ers there.
So, unless you want to listen to notzri pop, stick with Jewish music (never mind that almost all words of secular music aren’t kosher – and when a notzri sings words from Torah it is the old testament to them and it does not elevate the words).
