TLDR

Just found out about the Lifestyle mod, and fell in love with the music learning mechanics.
Sadly, all the addons that I thought would be cool to learn ingame are not B42 compatible. There is only few music addons for this mod on B42.
So, I learned how to make music addons, then took the sound files from the B41 mods that I liked, and fuze them into one.
I am planning to bring more songs to the mod so let me know aobut mods that are not compatible that you want in B42 or what you want to be added.
