It sounds like you're looking for the ringtone of the song (often spelled Chand Lamhe or Chand Lamhaat Ke Vaaste Hi Sahi ).
Would you like the exact timestamps to cut the ringtone, or help finding the song on a specific platform (Spotify/Apple Music)?
However, I can't directly provide a downloadable audio file or a direct link to a ringtone due to copyright and safety policies. But I can help you find it legally and safely. The song "Chand Lamhaat" (from the album Khamoshiyaan by Soham Naik and Akanksha Sharma ) is a popular choice for ringtones due to its soulful melody and poetic lyrics.
