lucifer (IRC): we currently use that one! Unfortunately, it doesn't always work, at least as expected. Below are a couple of the curl commands that shows the problem. I'm not entirely sure if it's several problems that are having the same effect, or the same one with different cases.

The first one is what should be a simple case, but the artist has a number of aliases and recording names depending on the stage of her career. With the first, 'Sasha Sloan' works when entered as the artist, but not the longer version, even though the former is the alias in MB.

The second is a case where there are multiple artists joined in an unusual manner (though still the way as entered into the MB database). This also returns no results.

mpdscribble does manage to resolve these, but it doesn't have a specific interface for ListenBrainz. It sends everything to the proxy, like with last.fm, where the data is then resolved. It's that process that I'm trying to emulate, but the API for the metadata seems not to like it. The given music has the metadata as entered into musicbrainz (it's organised with beets) but something is going wrong. 

Any help would be appreciated!

```bash
curl 'https://api.listenbrainz.org/1/metadata/lookup?artist_name=sasha+alex+sloan&recording_name=dancing+with+your+ghost' -L
curl 'https://api.listenbrainz.org/1/metadata/lookup?artist_name=selena+gomez+x+marshmello&recording_name=wolves' -L
