noitallmr, you didnt hear what feif un said: The khaliver rebbe was known for taking peasant folksongs and putting soul stirring jewish words to it, “transforming them ” into songs of kedusha. and those people in the know say that they are from the “holy of holies”. (personally not chassidish, but thats what they say)
the most famous of them is “solo kakosh mar” which was recently recorded by album JEP 5. great album, btw.
