The title is an article link that explains what’s going on. Essentially, Apple Music scans your computer for basically ANY sound file, either 1. matches it to a sound file on their cloud or 2. converts it to .mp3 and uploads it to the cloud. It then deletes all the files.
This means that:
1. If you have any in-progress tracks you’re working on in .wav? Too bad! They’re now in .mp3 and not on your computer anymore.
2. Do you have a rare live recording of a band? Too bad, because Apple has a lot of false positives and will often only match based on title and artist alone, so your personal live recording made for your personal use at a garage concert before they were famous is now replaced by the regular CD release that you’re not so hot on.
3. Do you have spotty wi-fi? Do you often work with the internet turned off, so you can be free of distraction? Well, welcome to life without music, because you can’t use the service without wi-fi.
Seriously DO NOT USE THIS SERVICE unless you want your ENTIRE personal music collection completely wiped in favor of an Apple controlled cloud service.
Whoa holy fuck
