Sonic Mania has offered some amazing musical tracks since it’s announcement but with the announcement of the Mirage Saloon Zone, a new original musical track made by Tee Lopes was produced. It sounds fantastic and you can listen to it with the above video link. The track was ripped and released online by ArfJason. While this might not be how it officially sounds, it mirrors how the track sounds in the gameplay footage it plays in online.
Even SEGA & Tee Loops are cool with this being music being released online to the fans.
