Strange Music

[Lexie361982]

For the past few days I've noticed this weird music start playing on my phone. I've googled the cause and tried different things but to no avail. I have gone into Safe Mode and the music stops. The only thing that stops it is if I restart my phone. I've ran malwarebytes and it says there's no virus. I've uninstalled Spotify, Amazon, and numerous other apps but it comes back. Like I was just watching a YouTube video and it started playing randomly. I've never heard it before but it always the same song or melody. No vocals, just music. I even thought it may be something to do with a theme I downloaded, so I got rid of it. I'm getting so frustrated with it. I don't know if my phone is connected to something else that is causing it. Help! It's like piano music if that helps.
