I was working on my own fork of Dynamic Music specifically for the 1.16 versions, having fixed some of the bugs relating to daytime, and called it DynamicMusic-Legacy. I was going to publish it as It's own mod but is there a chance we could collab on this fork and you could create two branches for my updated 1.16 versions?

If you want to make one 1.16 architectury branch you could do that too although I've never used the architectury api

I"ll open a 1.16 architectury branch! Just make a pull request into it and I'll take care of architectury

Should I just push the actual src folders for the forge and fabric version and their respective build scripts?

Oh you made two separate version !
Honestly maybe I should make 1.16.5-fabric and 1.16.5-forge branches then and keep theme separated

Thank you for that! I will be pushing the branches shortly!

Just know that I won't be able to look at your pull request before a few days but I'll get back to it as soon as possible!

That's ok. Thanks for the response!
