Apple Music downloader

Well the is in the title, but since there is a similiar idea, but in a spotify version, then maybe if it's possbile to be like a 2 in one application. But if its not that's ok. Also the design of the application can be the same as the youtube to mp3 converter with giving you a lot of freedom. like being able to edit the tags, and the option of keeping the format of the original format as it not the m4a format. And also the option to have different formats if the use would like to change it.
