Trombone Champ Charts
It's recommended to subscribe to the Steam Workshop items to get these charts. If you wish to use the files, however, they are also included here.
To install manually:
> Download the entire folder (not just the contents, the folder itself) or just download all the contents and put them in a folder
> Place the folder in your custom songs directory
> Press the reload button on the custom song location within Trombone Champ (or relaunch Trombone Champ)
> All done! Enjoy your new song(s)!
