Scriptable Plugins

[c]

Why not add some sort of scripting language/engine to MusicBee (such as Javascript or Lua) that can be used to develop plugins?
This way almost anyone can create plugins and creating them will in general be easier as you won't need to compile them.

this plugin might be enough for what you want:

otherwise someone else can easily enough write a COM wrapper around the MB api which could then be used for scripts
