However, I can provide some general information about the song "Creepin" by Metro Boomin, which was released in 2018 as part of his collaborative album with rapper 21 Savage, called "Not All Heroes Wear Capes". "Creepin" is a hard-hitting trap song that features savage lyrics from 21 Savage, while Metro Boomin's production includes a creepy-yet-catchy melody with heavy bass and eerie sound effects.
