RY: fine as in you’ve examined their neshama and found it to be unblemished? I find that hard to believe on more than one count…
Seriously, we can’t know squat about anybody’s penimios (and be in denial about ourself) but to deny that music can and does corrupt is being overly naive. Matisyahu has a powerful voice and obviously his own nisyonos — so even if you feel compelled to listen there’s no heter to promote his music as it does come with strings attached.
