Add Extended Music #192

Is your feature request related to a problem? Please describe.
I would really like to listen to these soundtracks' extended version when playing in MCC Island.

Describe the solution you'd like
Since Isaac Wilkins released the MCC and MCC Island Music Soundtracks' extended versions I think you should add them and maybe make it optional since the current music is really repetitive for a lot of OG people and this would be a great addition for those who got bored of the current short versions. Please make them high quality.

Describe alternatives you've considered
Noxcrew to add them directly to MCC Island but they probably won't do it due to the resourcepack size, not even with the Music toggle in MCCI settings.
