nexbeat

Docker app from DerKezorm's Repository

Overview

nexbeat finds music and requests it from Lidarr. A discover page recommends artists from what your library and each user already have, twenty main genres can be browsed, and every artist page shows the discography, the most played albums, similar artists and thirty second previews. A request adds the album to Lidarr and monitors just that one; a whole artist adds the studio albums and future releases. Everyone gets an account with a quota counted per request, optional approval, and invitations by email or as a link to pass on. The interface is available in English and German. nexbeat downloads nothing itself and never changes Lidarr settings. It needs a Lidarr you already run.

Find music and request it from Lidarr with one click.

Discover: recommendations based on the library, plus what is trending this week

nexbeat is a small, self-hosted companion to Lidarr, built in the spirit of Nexview: accounts with invitations, per-user quotas counted by request, optional approval, and a discovery page that recommends artists based on what the library and each user already have.

Status: early. It runs against a real Lidarr, but it is a small side project: expect rough edges.

The screenshots show a throwaway instance with a few well-known artists as its library.

What it does

  • Discover: "for you" and "because you listen to" rows from ListenBrainz similar-artist data, plus weekly trends. Artists already in Lidarr are left out.
  • Genres: browse twenty main genres. A genre page shows the most played artists and albums of that genre and related genres to follow. Artists in Lidarr stay in the list, marked as in the library.
  • Search artists and releases in MusicBrainz, browse discographies and similar artists, listen to 30 second previews.
  • Request a single album, EP or single. Unknown artists are added to Lidarr with only the requested album monitored.
  • Whole artists: one request for every studio album and future ones. Only offered when the metadata profile keeps Lidarr to official studio albums.
  • Quotas count requests per day, week or month. Rejected and failed requests do not count.
  • Accounts: invitations and password reset by email, or as a link to pass on when no mail server is set up.

nexbeat never changes Lidarr settings. It adds and monitors artists and albums and starts searches, nothing else.

Running with Docker

mkdir nexbeat && cd nexbeat
curl -O https://raw.githubusercontent.com/DerKezorm/nexbeat/main/docker-compose.yml
docker compose up -d

Open http://<your-host>:8030 and create the first account. It becomes the administrator. Then, under Settings:

  1. Lidarr: address, API key, root folder, quality and metadata profile. If users should be able to request whole artists, pick a metadata profile that allows official studio albums only. nexbeat checks this and says why when it does not fit.
  2. Mail (optional): for invitations and password resets. Without a mail server, nexbeat hands out the links for you to pass on.
  3. Users: invite people, set their quota and whether their requests need approval.

The Lidarr tab also shows a webhook address. Entered in Lidarr, it lets nexbeat notice finished downloads right away; without it, nexbeat checks every two minutes.

  • Updating: docker compose pull && docker compose up -d
  • Backing up: the whole data directory, the database and secret.key together. Without the key, the stored credentials cannot be read.
  • Images are built for amd64 and arm64. latest follows releases, main the current development state.

All requests for administrators: approve, reject or send again

Template configuration

WebUI PortPorttcp

Port you reach nexbeat at. Container port: 8000

Target
8000
Default
8030
Value
8030
Data (Container Path: /data)Pathrw

Holds the SQLite database with accounts, requests and settings, and the key that signs sessions. Keep it on a local disk, not on a network share.

Target
/data
Default
/mnt/user/appdata/nexbeat
Value
/mnt/user/appdata/nexbeat
PUIDVariable

User id that should own the files in /data. 99 is the Unraid default.

Default
99
Value
99
PGIDVariable

Group id that should own the files in /data. 100 is the Unraid default.

Default
100
Value
100
Time ZoneVariable

The zone the container runs in, for example Europe/Berlin. Quotas count in calendar days, weeks and months of this zone. Leave blank to use UTC.

Target
TZ
Container Port (host networking only)Variable

Leave this empty unless you switched Network Type to Host. In bridge mode the WebUI Port above already does the job and setting this will break it, because the mapping still points at 8000. On host networking the port inside the container is the port on your server, so use this to move nexbeat off 8000 if something else is already there.

Target
NEXBEAT_PORT
Secret KeyVariable

Signs sessions and encrypts the stored credentials, such as the Lidarr API key and the password of the mail server. Leave blank: nexbeat creates one on first start and keeps it in /data/secret.key. Back it up together with the data directory.

Target
NEXBEAT_SECRET_KEY
Secure CookieVariable

auto marks the session cookie Secure when the request arrived over https. Use on only if a proxy terminates TLS and forwards plain http, and never if nexbeat should also be reachable over http, or nobody stays signed in. off never marks it.

Target
NEXBEAT_COOKIE_SECURE
Default
auto
Value
auto
