v0.6.2

What’s New?

Album Artists

MS now tracks Album Artists and correctly scrobbles this info if the client supports it.

Targeted (Smarter) Polling for Play Durations #108

For polling sources that report track duration (Spotify), MS will now decrease polling interval near the beginning and end of the track in order to get more accurate “listened duration” and track start timestamp. NOTE: Spotify’s Automix feature may interfere with this.

Changelog

  • (player) Pad scrobble listen duration when confidence is high #108
  • (scrobbler) Use listenedFor when checking for existing scrobbles
  • (source) Smart interval calculation based on track position and end time #108

v0.6.1

What’s New?

Webscrobbler Source

The Webscrobbler browser extension has been added as a source using its native webhooks behavior.

Display and Controls for Queued/Dead Letter Scrobbles

Quietly implemented in 0.6.0, MS has two new control structures for making scrobbling more resilient to offline clients and network issues:

  • Queued Scrobbles – When a Source discovers a new Play it is added to a queue for each Client that should scrobble it. If the Client fails to scrobble due to networking or “showstopping” errors from the downstream API then it stopped processing the queue until the next heartbeat. This ensures all scrobbles are preserved until the downstream service is ready to accept scrobbles again.
  • Dead Letter Scrobbles – If the downstream service fails to scrobble for reasons that are expected by MS (EX Last.fm’s “ignored” response) then the Scrobble is added to the Dead Letter Queue, a queue of failed scrobbles.
    • The queue is retried a couple times on heartbeat to account for ephemeral issues downstream.
    • If scrobbles still fail the MS user can at least see what failed, when, and why. The queue display in the dashboard also allows users to retry scrobbling manually.

v0.6.0

What’s New?

UI Improvements and Now Playing

When a Source player state is detected a “Now Playing” player will render in the Source card showing how MS tracks plays for scrobbling.

The UI has been reworked to reduce whitespace, compact the layout, use headers more effectively, and improve wording/visualization.

Recently played tracks are now linked to their source (Spotify, Maloja) if MS can parse them.

Backend Tests and Scrobbling Fixes

A suite of tests have been added to test core backend functionality. These tests helped surface multiple bugs that should, now fixed, reduce duplicate scrobbles and improve consistency for all sources/clients.

Other Notable Improvements and Fixes

  • Backlog on startup is configurable #100
    • In a source config options property use "scrobbleBacklog": false to disable backlogging on startup
  • Enable/disable configs via property
    • In a source/client config at the top level use "enable": false" to disable using that config
  • Scrobbling deferred until track finishes playing or is changed
    • This ensures an accurate “listened to” time is recorded for the scrobble, rather than scrobbling as soon as “listened to” time is valid
    • “listened to” is now sent in Maloja scrobble payload
  • Jellyfin endpoint now accepts more header content-type values #101
  • Updated youtube source library to work better with non-chromium browsers #98

Breaking Changes

Docker Image Base Updated (Linuxserver.io)

  • Updates alpine 3.17 -> 3.18   * Main reason is to potentially fix DNS issues related to musl #88   * Bumps npm 9.1.2 -> 9.6.6

If you are using Portainer to manage containers you should remove all non-MS related ENVs from the container template before pulling the latest image.

Increased Scrobble Threshold Defaults #73

Previously, the default settings for scrobbling a track specified to scrobble if it was played for more than 30 seconds. This has been increased to:

  • Played more than 240 seconds (4 minutes) OR
  • More than 50% of the track played (for sources that support reporting track duration)

If you have scrobbleThresholds set in config.json or in individual source configs this does not affect you.

Increased Default Polling Interval

Due to the above change the default polling interval for sources have been adjusted like so:

  • Default Interval: 30s -> 10s
  • Max Interval: 60s -> 30s

This provides more accurate “listened to” recording and, generally, better source tracking resolution. This should not adversely affect your usage of each provider other than increasing bandwidth a little. These default settings can be overridden using the interval and maxInterval properties in individual source configs.

v0.5.2

What’s New?

MS now has a scheduled “heartbeat” that runs every 20 minutes. It’s purpose, for now, is to is start (or restart) sources that have stopped due to upstream issues. The use-case for a Source is:

  • request/polling retry attempts are low
  • source was initially OK (auth OK, initial communication OK)
  • and there is a non-auth related upstream communication issue

The heartbeat tasks will automatically try to restart polling for this Source so MS can recover from an upstream API communication error without user intervention.

Changelog

Features

  • (No Category) Schedule heartbeat task to restart sources that should be polling #6 #65 #93

Bug Fixes

  • (listenbrainz) Artist parsing joiner phrases must begin with non-word character #94
