I heard that there is a new movie named 'thank you' with the same copy-paste from hindi movie named 'thank you' and there is a song called 'kanchhi baadnam hui/bhayo darling timro lagi'. Director of the movie in an interview said it was simply a coincidence and they've don't know about the original song, and this is their original concept.

I've listened the title song of apabaad, it is nice and I liked it. But still it is influenced somewhat from other songs 'purani jeans' and 'papa kahete hain'.
