Well seeing how I was not able to get support here (Disappointing) . I'd like to help the next person, I found a very easy way to download all songs at once.
To download your Apple entire library using a smart playlist:
- Open the Music app on the desktop.
- Click the File menu in the menu bar.
- Select New.
- Click Smart Playlist
- Alternatively, you can create a new smart playlist with the keyboard shortcut Alt+Cmd+N.
- Click the first drop-down.
- Select Time.
- Select the second drop-down and click the Is Greater Than option.
- Ensure the time is set to 00:00. This will ensure that
the smart playlist contains every song longer than zero seconds in
length, which should be all of your music.
10.Make sure Limit to X Items is not checked.
11.Click OK and your playlist will be created.
12.Click the playlist name to rename it to something easily recognizable.
13.To download the playlist (and therefore your entire library) to your computer, tap the red Arrow. Depending on the size of your library, this may take some time.
- A -To download your entire library to your iPhone, open the Apple Music app on your iPhone.
- A-Tap the Library tab.
- A- Under Recently Added, you should see your newly created playlist.
- A- If it doesn’t appear, return to your desktop, open the Music app, and click Music in the menu bar.
- A- Select Settings (or Preferences) on older versions of macOS.
- A- Check Sync Library.
- A- Repeat steps 1A-3A and you should see your new playlist. Tap the playlist to open it.
- A-To download the playlist containing your entire library, tap the red Arrow.
- A- Depending on the size of your library, this may take some time.
Hope this helps!
