Purchased downloaded music not uploading to Apple Music on Mac, but appears in other devices

iCloud Music Library, which underpins Apple Music and iTunes Match, won't accept content from a different account. I suspect changing stores, albeit with the same Apple ID, effectively creates a different account. You would need to generate new copies of your old purchases that no longer contain a reference to your account in the store, so that these can be absorbed into your cloud library in the same way as say CD rips.

See Convert a song to a different file format with the Apple Music app or iTunes for Windows - Apple Support.

You might want to try RE-downloading the songs to Mac: Apple support have an article online that may help:

Redownload music - Apple Support

Troubleshooting if needed:

"Learn what to do if you can't redownload an item or if you don't see the item in your purchases.

See: If there's an issue when you redownload apps, movies, or other content from Apple - Apple Support

The unable to add folder is the destination for items that are not considered compatible with Music. For third party content I would suggest fetching new copies, re-ripping, etc. For purchases deleting and redownloading would normally work, but that may be complicated if you have changed regions and currently have any store credit or an Apple Music/iTunes Match subscription. Perhaps you can retrieve working copies from one of the devices where those tracks play? See Recover your iTunes library from your iPod or iOS device - Apple Community for suggestions. I'd probably try iFunBox to start with.

New Location:

As for Allen iTunes Store purchases, if you’ve relocated to a different country, you’d have to purchase these again. If these are Home Music files, then use Apple Music, and they’ll sync across all your devices.

Thank you for joining the discussion, tt2! Grateful for the light you throw on this issue! 😀

I have Apple Music. I recently moved and switched all my devices/stores to a new country and restarted my subscription.[...]"

Troubleshooting Loss of Music:

Relocation is the Culprit Here:

iTunes purchased items are only usable in the country/region in which they were purchased. So, having relocated, you must purchase these again :(

If something shows in the iTunes Store as purchased (instead of a play button or the price) that suggests an item hidden from your purchase history. When you are signed into your Apple ID you should see locally stored content on that device, along with your unhidden purchase history, and anything that is in your iCloud Music Library if you have a subscription to Apple Music or iTunes Match. Changing stores won't have changed what was already on your computer or device, but may impact what can be seen of your purchase history, and what is held in iCloud Music Library. In you library use the Songs view and enable the Cloud Status column. This should let you see which tracks are waiting, ineligible, removed, error, etc. For ineligible tracks making fresh copies is generally the way to go.
