Kaisa Sama - Officer by Kumar Sanu, Alka Yagnik

Kaisa Sama - Officer is the kind of song that earns its place in a playlist and then refuses to leave. Deepak Choudhary has a history of strong work, and the music on Kaisa Sama - Officer is among the most memorable of it.

There are singers who perform songs and singers who live inside them. On Kaisa Sama - Officer, Kumar Sanu, Alka Yagnik clearly belongs in the second group. The chemistry of a talented ensemble cast is embedded in every moment of Kaisa Sama - Officer, making it as much a performance as a song.

The song dates from 2001, but nothing about it sounds dated — the emotions it captures are not tied to a moment. The mood of the track shifts subtly as it progresses, giving even a single listen a sense of journey.

Running to 5:30, the song is exactly as long as it needs to be, which is the hardest length for a songwriter to find. The song continues to find new listeners, which is the surest sign that it was made with something genuine at its core.
