Answer
Kishore Kumar's unreleased last song, "Door Rah Kar Bhi," was sold for a staggering ₹15.6 lakh in 2012. The song, recorded in 1987 but never released, was discovered on an old cassette tape and auctioned off by Kumar's family. The winning bid came from a music collector who recognized the song's historical significance and its value as a rare recording from one of India's most beloved singers.
