TuneinCrew is a command line radio creator for The Crew. It is designed to take a simple XML file containing the data needed and convert it into a compatible PitCrew mod to be able to listen to your custom music in-game.
Since the game uses FMOD, it can also let you customize your songs with effects pertaining to your vehicle's speed and if you're viewing the map or not.
How to Use

A massive thank you goes to Guki92 for figuring out how to add radio stations to the game, and also with testing this tool for many, many hours catching a lot of my mistakes.
