Thanks to Erik Jälevik for requesting this feature!
Aural can now scrobble tracks you play to your Last.fm account!
Love/Unlove tracks
In addition to scrobbling, Aural can also "love" or "unlove" tracks that you add to / remove from the Aural "Favorites" list.
One-time authentication / setup
In order to use these features, go to Aural > Preferences > Metadata, and first follow the instructions on the preferences panel to authenticate with Last.fm and provide permission to Aural to use Last.fm's web services (in your web browser). This is a one-time setup process. Then, simply check the relevant checkboxes to enable scrobbling and the love/unlove feature.
Instructions for 2-step authentication on preferences panel
Browser setup (before granting permission)
NOTE - When Last.fm opens in your web browser, you will need to log into your Last.fm account if you are not already logged in. Then proceed as shown in the images below.
Browser setup (after granting permission)
The rules for a valid scrobble
In order to consider playback of a track a "valid scrobble", certain conditions must be met in terms of track duration and playback duration.
See https://www.last.fm/api/scrobbling#when-is-a-scrobble-a-scrobble for details.
Caching and retrying of failed scrobble attempts
If / when scrobble attempts fail due to loss of network connectivity or any other reasons, Aural will cache the failed attempts and try to scrobble 4 more times per track (for a total of 5 attempts), upon subsequent app launches. Any failed scrobbles more than 2 weeks old will automatically be invalidated.
Re-authenticating to refresh the Session Key
When Aural authenticates with Last.fm, it obtains a Session Key that is persisted and reused indefinitely. In the unlikely scenario that the Session Key no longer works (you notice that scrobbling no longer occurs), it is recommended to re-authenticate and obtain a fresh Session Key, using the "Re-Authenticate" button in the relevant preferences panel. This will allow you to repeat the one-time setup you did earlier.
