A tool for people who manage CDs with iTunes.Sometimes I cant remember what CD I have on the go, so if I only know the list of jacket copies, I can prevent duplicate purchases.The folder structure when the save destination such as mp3 is / iTunes Media / Music / is reproduced as it is.If you are in a Windows environment, support tools are also available, so you can reduce the burden on your smartphone.If the artwork is embedded, it will be extracted automatically.Please see HP for details.It can be used as a player, but its just a bonus.If you have mp3 data saved in / iTunes Media / Music /, you can play it by copying the folder under Music.Currently, it is only a bonus, but if there are many requests, we will consider it.It doesnt do anything by itself.
