I choose old folk Punjabi song " Jugni " by late Alam Lohar .
I picked this song due to unique instrument " Chimta" . You can't get this instrument in music in any other Singer. This instrument introduce when very few were there and it becomes the identity of this Singer. Jugni itself a great lyric which sung by tens of singers later but the original voice of Alam Lohar made it more melodious and cultural.
