There are few songs that can leave one with a lump in the throat.This is one such song.Pretty old one(maybe 3-4 years back) ,though,by a Pakistani band called Fuzon.
Song is titled “Khamaj”. Think the lyrics are in Urdu.Have been trying to figure out the meaning but quite unsuccessful so far 
The only part that I understood was this :
“Pyaar tumhein kitnaa karte hai,
Pyaar tumhein kitnaa karte hai,
Tum yeh samajh nahi paaoge,
Tum yeh samajh nahi paaoge ..”.
Btw,is Khamaj the name of some raagam ??

/ August 28, 2008‘Khamaj’ it’s the name of a musical mode. and also is a very Indian thing, strange how fuzon did it, but theyve done a good job. if am not wrong this song was released way back in 2000-01 in Pakistan.
