Wait, I should check if the song "Athukum Mela" was actually released as a standalone. Some might confuse it with another song. Let me verify that. Yes, it's part of the movie's soundtrack and available on music streaming services. Also, the term "UPD" in the query might be a typo, maybe "update" or referring to a specific aspect of the song. Since the user wrote "music upd," perhaps they meant the latest version or update, but it's better not to assume. Focus on the song itself.
