Alternatively, maybe the user misspelled the names. For example, "Mouli" could be "Mouli" as in Kalyani Mouli, an Indian playback singer? Or maybe it's a part of a song title. Let me try to find any songs related to these names.
Wait, another angle: "Ringtone" suggests it's a mobile phone ringtone. Maybe it's a popular melody extracted from a song composed by someone. Kailash Rana is a director, so maybe the ringtone is from a movie he directed. If the movie's music was composed by someone else, maybe "Shiv Chandra Mouli" is the composer. But I'm not finding any direct connections. Kailash Rana Shiv Chandra Mouli Ringtone
