Add automix flag (always play random music from the current playlist)

Without this feature, spotify_player plays just a mix from the last 50 songs added to my liked playlist.

50 comes from tracks_playback_limit config (https://github.com/aome510/spotify-player/blob/master/docs/config.md#general). You can try to increase the value to allow creating tracks playback of more songs. Just a note that a big value will not work because there is a limit on number of tracks specified in a tracks playback API request.

Should have added a note to how tracks_playback_limit works. In short, the app will pick an interval with at most tracks_playback_limit songs containing the selected song to start a tracks playback.

To clarify, tracks playback is a playback with a bunch of songs unlike context playback (artist, playlist, album). "liked songs" doesn't count as a playlist. Playing song from "liked songs" page will start a tracks playback and invoking CurrentlyPlayingContextPage command will lead you to a cannot determine current page's context page.

Thanks for the clarification.
This might be a dump question, but why do we use the tracks playback, which creates a subset of songs as I understand, instead of picking random songs from the page (e.g. Liked Songs) where they don't provide a context playback? Wouldn't this solve the limitation of the Spotify API, that we can only create tracks playback with up to 100 songs?

The main reason is to avoid possible confusion when user doesn't have shuffle on.

Not really as the playback still contains a subset of the liked songs, e.g if you listen for a long time, it will loop between pre-selected 100 songs.

automix behaviour can be supported by implementing a custom logic to invoke tracks playback by "batches". For example, after finish playing a 50-song playback, the app will pick another "batch" of 50 songs to start the next tracks playback.

I would think mixautowould only apply when shuffle is enabled. When not shuffling, we just have an ordered playback.

Yes, but wouldn't it always be the same 100 songs, just ordered differently?
E.g. having a tracks_playback_limit of 1 will always result in the same song.

This would also be a great feature to have.

I am not a rust dev, but I can look into it.

Yeah, exactly =).

Great! Lmk if you have a PR up. It's always good to learn Rust IMO 😎

+1, it's very annoying that shuffle only plays songs from around the one I select manually
