I have music module files of various formats, and I am encountering a strange file association error on OS X 10.11.4. I want XM and IT modules associated with VLC. I want MOD and S3M modules associated with Audio Overload. There are more which I mostly want associated with Audio Overload, but associated with VLC if it's a format Audio Overload doesn't understand, like the ones already listed as me wanting associated with VLC. For some strange reason, as an example, each time I try to change associations for XM, MOD will also be affected. I thought file associations functioned based off the extension, but this is just WTF?! How do I get the associations to work how they are supposed to?!
