My point is, some of the catchiest music today and of the past 60 years is totally unkosher...basically satanic.
I think at the time of the Temple the music will be as enticing as the most catchiest of the century but totally kosher.
If you look at things like rap today, there is a reason why people like it... the beats...it is because there is rythm and bass...but the lyrical inspiration mostly comes from the sitra achra.
There is a reason why people like country music too...the twang of the guitar...
If you look at the great orchestras of Europe which 'cultured' people love so much (Bach, Bethoven etc...) you can see there is great orchestration and heavily nuanced music, but at the soul of it, it speaks of a different type of ideal or zeitgesit.
It is hard to explain...
But my theory is that when the Temple stands, the music will incorporate all the elements of what makes these varying types of music popular into one great symphony which will basically be irresistible...As irresistible as the odors of the incense etc...
That's how I picture it anyways...The soul of music went into exile when the Temple was destroyed.
In my opinion this is one of the challenges of the generation...bringing the soul of music back to Temple worship, or worship of God in a way that is undeniable. That means everything...rythm, strings, flutes, drums...it has to be superior to all other music...probably would be the most effective form of kiruv if it is done right.
