[Feat]: Youtube-dl

[nrgbistro]

Is your feature request related to a problem? Please describe.
I don't current have a paid subscription to tidal or deezer. While they do seem valuable especially for flac files, I would be ok with downloading directly from youtube.

Describe the solution you'd like
It would be nice if it was possible to use Youtube-dl as a backup if tidal and deezer downloads fail.

Describe alternatives you've considered
I've tried adding more indexers to lidarr but cannot find some of the more niche albums that I listen to. Youtube certainly has individual songs that could be easily searched for.

Pretty sure, you can use deezer for free, just limited to the free tier quality... Might even be the same for tidal...

I would welcome a PR for this, but I don't think this is something I'm going to work on honestly. Lidarr relies on full albums, not single songs, so it doesn't seem like it would fit at all for this and would be too cumbersome to support/develop.

Deezer is free but limits quality to 128K MP3. I don't see YouTube being better than this. Tidal free says it is limited to 160k for songs.

Although it seems deezer free is an already supported method. Given that for videos the implementation is already there, an adaptation to trigger as well for just the audio could help to bring this docker more mainstream remove yet another barrier of adoption (deezer account).

PS: I haven't seen a free Tidal plan, only 30-days trial. https://tidal.com/pricing

Doubt this will ever be implemented, I'm not working on it and don't expect that anyone else will... I don't believe the resources required to make it work exists and YouTube is more focused on tracks, not albums which also makes it a deal breaker.

I --for one-- came here because I was searching for precisely this functionality. There are a lot of songs out there that I love which aren't on now nor may ever appear on mainstream streaming platforms, and I'd much, much rather have some copy of my song than none at all. I'd love the option to use something like ytmdl or scdl as a fallback in case the track couldn't be reliably located on the more organized services.

I understand that it wouldn't be trivial to integrate because of the expectation that albums could be found, but nonetheless here is the functionality I imagine precisely that could work:

1. If configured, any track that cannot be found could be searched for on youtube and/or soundcloud by "name - album - artist" on those platforms and the first x (default: 1) results could be queued for download. Ideally, I imagine a simple algorithm could be used to take the expected name and the name of the first result and generate a confidence score for it, only downloading the result with the highest confidence of matching if it is over a certain (user-specified) threshold. However for sake of simplicity, just the top result or results of the fallback service/s could be downloaded.
2. They'd be tagged with fallback + youtube or soundcloud.
3. At a regular interval, say every day, week, or month, they could be preconfigured to be searched for again on the higher-quality sources.

This should now be resolved via this commit: b14973c

Read the commit details/description to understand how to use it properly...

[RandomNinjaAtk]

Please confirm this is resolved, if not I will auto-close in the near future. As far as I can tell its working...

So I can either user deezer or freyr, but freyr will not be used automatically as a third option automatically if using tidal and deezer and both fail to download?

Correct, freyr doesn't support tidal links, so It couldn't be used as a fallback for tidal. Also this is a simple fix, making it operate in the manor your suggesting would require more work that I simply don't have the cycles for... I was only able to implement this because I found a piece a software that was easy enough to insert and not make that many changes...
