There's a genre called Rabindrasangeet in music that single-handedly changed the entire course of music here for a while.
Here's my favourite of them all :
Mayabono Biharini (Somlata)
O jonaki ki shukhe (Shan)
Ogo Bideshini (ion remember the particular track)
Some non-rabindrasangeets that I like :
Prithivi ta chhoto hote hote
Bella Bose
Nilanjo......
