A mod which adds a Bad Apple joker to Balatro Requires Steammodded
The joker does not alter sound, since I thought that would be annoying, but does play all of bad apple. The joker also has a hidden positive effect while held, which you can either figure out on your own or be boring and read the source code. To install, go to releases, download BadApple.zip, unzip and place all files in C:/Users/your username/AppData/Roaming/Balatro/Mods/ (you may have to make this folder)
