O Chand by Rupankar Bagchi

Rupankar Bagchi has delivered memorable performances before, but O Chand sits comfortably among the very best. What makes O Chand musically distinctive is the composition by Rupankar Bagchi, which balances simplicity with depth.

There are singers who perform songs and singers who live inside them. On O Chand, Rupankar Bagchi clearly belongs in the second group. Featuring a talented ensemble cast, the song carries the weight of the film's emotional arc and delivers it with conviction.

The song dates from 2017, 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 4:42, the song is exactly as long as it needs to be, which is the hardest length for a songwriter to find. It is, simply, one of the better songs to come from Bengali in recent memory — and the numbers agree.
