Tags not recognized by beets

[Gwouigwoui]

Hi!

I'm in the process of importing my collection. One of the issues I'm encountering concerns the BPM tag. When importing some files (autotagging on), when I look at them in MusicBee they have two differents BPMs. After looking a bit more in-depth, here's the situation:

• M4A files
• two differents tags: "BPM" and "tmpo" when I look at the tag inspector in MusicBee, but they're effectively displayed in the same field. Setting the "BPM" in the metadata editor to empty and saving empties tmpo, but not BPM. To remove the "BPM" tag I need to go in the tag inspector.
• when using the beets "info" plugin, the "BPM" tag isn't listed, only the "tmpo" one.

Is there anything I can do? I'd love to be able to scrap that field automatically on import.

Thanks!
