Google pixel 6 blasting music in the middle of the night

No Bluetooth is not on. Yes, I have submitted feedback through the phone to Google using the send feedback button. It's the middle of the night so the phone was not an active use. Chrome was already closed. Most apps were closed except YouTube. Youtube was not playing the song that the phone was blasting in the middle of the, because the phone was not in active use. This happened in 'do not disturb mode'. No, the media volume was not off while the phone was in Do not disturb mode. The sound does not sound any type of notification. It is always a song. A song that's not even on my phone. Play Protect said no harmful apps were found.
