Letakein Girl:
What makes the ability to affect your emotions a problem?
(Are any “negative” emotions caused by music, such
as the example you gave of anger, “real?”)
Music affects your emotions, and emotions affect your spiritual state. However, those emotional effects are temporary, perhaps even momentary – perhaps the spiritual effects, if any, also are?
Your personal feelings about non-Jewish singers are arguably admirable [that’s a positive statement 🙂 ], but cannot be used as an explanation of why listening to non-Jewish music is objectively wrong.
