After cleaning Apple Music traces in the R-Wipe & Clean, I ran another cleaner, which found several cache files left by the Apple Music app.
It was also discovered that one of the Apple Music app's databases contains URLs of iTunes sites where I had made purchases.

Thank you for the information. I've passed this to our developers.
