Is there a way to know if a reels is embedded with music over the original audio?

[Julian-BFacal]

I am trying to distinguish the reels that have some music embedded over the top of the user talking. Ive seen that in clips_metadata we have a music_info that clearly shows when a post has a song selected. However, this music_info has data both when the sound fully overlaps the actual sound and when it is added as background music. Is there any way to know in which cases the music if the only sound being provided?

I want to distinguish between them so I avoid making useless transcriptions of the audio to text when there is only a song.
