Re: [mb-users] Track duration is None

Okay, so, first of all, python-musicbrainz2 is deprecated, since the webservice version it uses (/ws/1) is deprecated. So I'd suggest moving away from that. However:

https://musicbrainz.org/ws/1/release/?discid=Uet7Ne0jNNwhz206YC0rPlDJELw- is the url it constructs initially. You can see the result it found.

Issue: that endpoint includes CDStubs[1] by default. As you can see, https://musicbrainz.org/ws/1/release/?discid=Uet7Ne0jNNwhz206YC0rPlDJELw-&cdstubs=no does not include that result. Also, CDStubs don't support many of the various ?inc parameters, and they don't have much info.

The CDStub is: https://musicbrainz.org/cdstub/Uet7Ne0jNNwhz206YC0rPlDJELw-

I'm not sure why it's not including durations, but I'd bet it's because it's a CDStub.

In general, I'd recommend a.) moving away from python-musicbrainz2 and /ws/1, b.) if you must, figure out the proper way to exclude CDStubs, and c.) sometimes things just don't have durations even after all that. So you'll just have to account for that somewhere :)

Hopefully this helps.
