Spent most of this time deciding the tech stack I wanted to use for this project. I knew I was going to be using .NET, so my main concern was finding a library that would make audio playback easy and crossplatform. I settled on SDL3 (and SDL3_mixer) because bindings for that were readily available, but I have to write a lot of wrappers around SDL because it uses a lot of nasty C things like pointers and stuff.
I ended up writing a little demo C# program to get my head around audio decoding and a couple concepts from SDL. Everything after this will be making the music player for real
