STR: 1. Take two MP3 files which differ slightly (such as in their metadata). 2. Compare them using diffoscope. 3. View the resulting differences. Expected: Diffoscope supports MP3 files and I get a useful comparison view. Actual: I get only a hexdump (which has many differences). While not important for my daily work, this case up today and having diffoscope support here would have been useful.
