A simple python module for sorting and combining lists of music.
TODO * add a test flag for validating music entries * each entry must have a band name, album name, year, and format * validate year seems reasonable e.g. not before say 1930 or after current year * format should be validated against a known list of formats * validation for one file at a time * possibly add a config to define the entry's format * better logging (i.e. there is none)
