To me, Behka seems to be in the genre of Khoya Khoya Rahta Hai of Doli Saja Ke Rakhna. Similar type of mahaul - thoughts and fantasies about the lady he loves.
When we hear an ARR song, we often wish that ARR comes up with another song of that type, and when ARR actually eventually creates another song in that genre, it is still so different and enjoyable in its own way that I wonder how can he come up with such a different song in the same genre. How could he prevent himself from getting carried away by his memories of the previous songs and not repeat things from the old song, and give an altogether different song. It takes several hearings for me to find the core of the song and match it to find that it is a sequel of some previous song. Our man is great. -- Rawat
