Last time i checked alot of the gerrer marches were all nepolians marches.
Also besides that alot of chasidish miggunim are from non jewish sources
the zohar says that all tunes can be uplifted for spiritual needs
its the words that can be trief
The question here is are the fast rockin songs with hebrew words really spiritualy stirring or just some heter to listen to them?
The rockin chabad niggun without words, is alot more soul searching then the words of tehillem put into a rockin song
