Whisper bogs down in hard-to-transcribe singing

[ArthurPeabody]

I notice that difficult-to-understand singing bogs Whisper down. Impossible-to-understand singing Whisper calls '[music]' without taking a lot of time. Easy-to-understand singing Whisper transcribes about as well as talking. I terminated a transcription, restarted it after the difficult-to-understand singing.
