beaTunes works best with unencrypted music you own. If you are using the streaming service Apple Music., you are just renting the music and the audio can only be read be Apple products. Unfortunately, that's how Apple wants it.
The only way beaTunes can find the BPM for DRM-encrypted music is by looking up values via the files' metadata, i.e. title , album, etc.
So to get the BPMs, you might want to select some songs (or choose analyze all) and then—in the analysis options dialog—make sure to check the option "Use online resources" for all tasks you are interested in (see attached screenshot). That way beaTunes first tries to look up BPM values instead of computing them using your files.
Hope this helps—let me know how this works for you,
