I'm not sure if anyone talked about these, but there are a few library music playlists on the Mozart Edition website. These playlists are usually sorted into different categories (i.e. "Featuring Piano", "Scotland", "Spring", etc.). These usually feature a couple tracks from their catalog. Recently (I'm not sure when), they've released 2 new playlists, being "Countryside" and "City". When you go to a playlist's page, you might notice that there are no composers listed there, only orchestra credits. The composer credits can be seen on the playlist metadata. You can find the metadata for each of the playlists here: editionuk.online/metadata
You can download these tracks easily via Google Chrome's developer tools, similar to APM's site. I'm not sure how often they will release playlists, but I'm hoping to see more of them on their site in the future.
Here's the link for the playlists:
