I was surprised not to find cantata[1], another MPD graphical client, on the list. Used it for the past three years, despite it being unmaintained for quite some time now. The client is very featureful, allows downloading lyrics and covers automatically (TBF had many mismatches, like downloading some Gillette ad as an Eminem's album cover). Most important to me is the ability to listen do directories and not artists/albums, which cantata does perfectly. Recently nixpkgs replaced cantata with a fork[2], so cantata is kind of online again.
Bubblewrap seems to be much more popular[^1], personally this is the first time I heard about landrun

I wanted to say Haskell with shh[^1] and stack's or nix's shebangs[^2][^3], but interpreted haskell is not particularly fast.
Also I think a Python script is reasonable if you use a type-checker with full type annotations, although they are not a silver bullet. For most scripts I use fish, which is my preferred interactive shell too.

On a side note, if you were to use nix's shebang for haskell scripts with dependencies, you should be using https://github.com/tomberek/- instead of impure inputs, because it allows for cached evaluation. I personally cloned the repo to my personal gitlab account, since it's small and should never change
