Importing from Last.fm¶

In addition to scrobbling plays to Last.fm, Musium can import listens from Last.fm. These listens count towards playcounts which are used to rank trending tracks and discoveries. This way, these features can be useful even when you haven’t been using Musium for a long time, or when you listen with other players in addition to Musium.

Authenticating¶

Follow the authentication steps as for scrobbling. To import listens you do not need the LAST_FM_SECRET and LAST_FM_SESSION_KEY, only the LAST_FM_API_KEY.

Full import¶

The first time you import listens, you will want to import your full listening history. This is done as follows:

tools/scrobble.py lastfm import full /db_path/musium.sqlite3 «username»

The file path is db_path as configured, and «username» is your Last.fm username. This command will then fill the lastfm_listens table in the database.

Incremental import¶

After a full import, an incremental import is typically sufficient. An incremental import will import all listens in the two weeks before the latest listen in the database. If you run an incremental import regularly (e.g. daily with a systemd timer) then this should be sufficient even for cached listens that are submitted later. In case of missed listens, you can simply do a full import again. An import will only ever add listens, it will never erase already imported listens. To perform an incremental import:

tools/scrobble.py lastfm import incremental \
  /db_path/musium.sqlite3 «username»

Integrated syncing¶

The scrobble script has a subcommand lastfm sync which performs a lastfm scrobble followed by a lastfm import incremental. It is useful for use with systemd, as shown below.

With systemd¶

As with scrobbling, it is possible to run the import as a one-shot systemd unit, which can then be triggered by a systemd timer, or started as part of the post-idle script. The setup would be the same as for scrobbling, except instead of calling lastfm scrobble, the unit’s ExecStart= would use lastfm sync.

Data¶

All imported Last.fm scrobbles are stored in the lastfm_listens table in the database. Aside for usage in Musium, this table acts as a local backup of your Last.fm listens. You own your data.
