First, the song is from Bollywood, probably from a movie set in a traditional or festive context since the title mentions "Mangal Raat" which I think refers to the engagement ceremony. The user mentioned it's exclusive, maybe meaning it's a popular or trending song right now. The song's title "Woh Mangal Raat Suhani Thi" translates to "That Auspicious Night Was Beautiful, She Was the One to Marry." So, the song probably revolves around a romantic moment at an engagement ceremony.
