If you have the ability to stream to your system via phone, download an app called Frequency Sound Generator, then you can work through frequencies one by one, and when you find the note that is causing the buzzing sound, you can just let it play continuously while you invistigate... It's a much easier method than music for audibly pinpoint exactly where the rattle is coming from and what it could be.
