feat: Scrobbling from phone (Android) to multi-scrobbler ? (not a bug)

[iluvatyr]

Hello,

it is not really a bug, but I am a bit confused since I cannot find any option on how to scrobble from my (android)- phone to multi-scrobbler.

Does multi-scrobbler offer some endpoints that are commonly used so that it is possible to scrobble to multi-scrobbler via them (like maloja does) ? I want to use multiscrobbler as the "central station" for all my scrobbles and without this option, I can't do that.

I am using pano-scrobbler-android-app to scrobble some from some apps on my android phone and I'm not sure how I would scrobble to multi-scrobbler. It only offers a custom listenbrainz URL. Or are there other apps that can scrobble to multi-scrobbler?

Thanks for any help

MS does not currently have endpoints for general scrobbling. It's something I've played with in the past and there's even an old branch that implements a Listenbrainz endpoint but I haven't fully implemented this kind of feature yet. There's more designing that's required before the LZ branch is merged and it hasn't been a priority. I'll think about how best to approach this.

In the meantime there is a direct scrobble integration for Webscrobbler or you could use last.fm/LZ as a source to relay scrobbles to another scrobbler.

@iluvatyr please try out docker image foxxmd/multi-scrobbler:pr-281 to use multi-scrobbler with a custom listenbrainz URL.

To configure it use either ENV like

LZENDPOINT_ENABLE=true

or as a file config with endpointlz.json

[
  {
    "name": "MyLZ",
    "enable": true,
    "data": {
    }
  }
]

Then, in your android app use one of these for your custom listenbrainz URL:

MSDashboardHost/api/listenbrainz
MSDashboardHost/1/submit-listens

MSDashboardHost is whatever you'd normally use to access MS web ui (localhost:9078 or w/e domain)

If the app does not allow specifying the full URL then it's probably appending /1/submit-listens itself so just use your dashboard URL.

Please keep in mind that for scrobbling to work your phone must be able to reach the MS dashboard.

@FoxxMD

I downloaded the specified docker image and added the listenbrainz endpoint. In my android app (pano scrobbler) I need to add an authentication token too though. What would that be?

[FoxxMD]

If a token is required then use any value you want and add this to config:

As ENV

LZE_TOKEN=anything

or config

[
  {
    "name": "MyLZ",
    "enable": true,
    "data": {
       "token": "anything"
    }
  }
]

[iluvatyr]

Thank you!
I added the token to the config as stated.

I'm not sure what I'm doing wrong now though.
On my Android phone I added my MSDashboardHost (Which is the dashboard URL I'm using with a FQDN, e.g. https://mscrob.mydomain.com

I also added the token I specified.
When I do that in Pano scrobbler it says an error message when trying to set up the custom listenbrainz as follows:

Expected response body of the type "class YH.oc (Kotlin reflection is not available)

My reverse proxy tracks following url when I hit this:
IP - - [14/Mar/2025:16:26:15 +0100]"GET /1/validate-token HTTP/1.1" 200 894"-" MSDashboardHost "Pano Scrobbler

Using https://mscrob.mydomain.com/api/listenbrainz gives a 405 error.
Using https://mscrob.mydomain.com/1/submit-listen is the same as described without the /1/submit-listen added.

[FoxxMD]

Interesting...looks like I may have missed some part of the listenbrainz api, based on that url.

@iluvatyr Please upda te to the newest foxxmd/multi-scrobbler:pr-281 image and let me know if that fixes things.

@FoxxMD it is fixed. It discovered the track correctly. Amazing! Thank you for all these additions and the responsiveness that is the best I have ever seen!
