I've been wanting to look into scripting but haven't found the time yet.

The answer I came up with was to run fdupes then used sed to remove all
lines containing jpeg, jpg, txt, png, etc. from the output file.
What I'm left with is only mp3. ogg, flac, m4a, etc.
Probably not the most elegant solution but it worked.

Thanks for your input.
