Description
CMS21 - Tiered Playlist Engine (TPE) is a lightweight, portable tool that brings true radio randomization to Car Mechanic Simulator 2021.
The game reads music files from the User folder in alphabetical order, which means your carefully curated playlist always plays in the same sequence. TPE solves this by dynamically renaming and reorganizing your music files giving you a fresh, shuffled playlist every time you launch the game.
With a simple dark-mode GUI, real-time console logging, and two shuffle modes (General and By Station), TPE puts you in full control of your in-game radio experience. No manual file editing, no complex setup – just select your stations, choose a mode, and play.
