The difference from the old iTunes scripts are that this is including two scripts, one is for the official iTunes API, but using the JSON parser instead of text based as earlier. It should be pretty safe to use at any time. I have also added a "Apple Music" parser, but it is not using Apple API, but rather exploring that Apple is adding most data inside a JSON structure in their web pages. How stable that will be, is yet to be seen, but it has remained this way for quite some time. What you will receive in addition to the official API is composer(s), curator comments, ISRC, work name, more detailed genres and label information etc. It is also possible to make more adjustments to the script, so you can make separate entries for the artists and composers. As well you could add all the urls to Apples various pages for each of them.
