Anupam Roy: Tomaar Bhetor Theke (Song)

I happened to come across this song by chance. Never heard it before, and never saw any mention of it earlier, and Im really surprised why! A song that's just about 07 lines long, feels as if sung at a time when someone's sitting on a window seat, looking out on a rain-clad day....a half-finished coffee mug by the side, guitar lying down in one corner, slightly tilted...eyes looking out but not really seeing...
