Here's my latest favorite...

The song is "Beete Lamhein" from the movie "The Train". I haven't seriously thought about watching the movie but I loved the song. Hands up for the great K.K :)

Dard mein bhi yeh lab muskura jaate hai..
Beete lamhein humein jab bhi yaad aate hai...2

Chand lamhaat ke vaaste hi sahi
Mushkura kar mili thi mujhe zindagi ...2
Teri aagosh din the mere kate
Teri baaahon mein thi mere raatien kati

Aaj bhi jab woh pal mujhko yaad aate hain
Dil se saare gumo ko bhoola jate hai

Dard mein bhi yeh lab muskura jaate hai
Beete lamhein humein jab bhi yaad aate hai
Beete lamheinnnnn

Mere kandhein mein sar ko Jukana Tera
Mere sene mein khud ko chupana teraa
Aake mere panaho mein shaam-o-seher
Kanch ki trah woh tut jana tera

Aaj bhi jab woh manzar nazar aate hai
Dil ki viraniyon ko mita jate hai

Dard mein bhi yeh lab muskura jaate hai
Beet lamhein humein jab bhi yaad aate hai
Beete lamheinnnnn
Dard Mein …..Beete lamheinnnnn
