These are the songs which are my personal best

Channa Mereya
No other song could be on the top place when we talk about the best sad songs in Bollywood. The song is in the movie "Ae Dil Hai Muskil" singed by Arijit Singh this song is something divine to ears.

Judaai
Once again its Arijit singh’s voice along with the classical maestro Rekha Bhardwaj “Judaai” is one of the finest sad song from the movie Badlapur which will make you lost in the people you miss the most.

Maa
The song “Maa” from the movie Tare Zameen Par is one of my personal best on the list as this song perfectly demonstrates the beautiful relation of a son with his mother. It is singed by one of the most renowned singer in Bollywood “KK”.

Dard
This song is from the movie “Sarabjit” and singed by Sonu Nigam and is really an exceptional one. The beats, the voice, the lyrics each and everything is simply perfect. The song is based on the emotions of Sarabjit who was been arrested by the Pakistan Army because they were in a misconception that he was spying for years.
