Yes and no. A lot of sorting and optimizing processes can be done via scripts. For example, I had chatgpt generate one that finds audio streams in videos that are not in the language I need. Manual verification and then let another script remove the remaining lists streams that I don’t need.

I commented that I have experience with similar tools and that is why I chose others. I never said anything about this particular one.

Why would I need to look into this particular tool right now? I don’t need it and it has no real relevance to what I was saying either.

In my experience, most of these tools usually only search the equivalent song on YouTube ans download it from there. Which can cause some trouble when the algorithm finds some cover etc instead of the original thing. Plus the lossless issue. For me personally, it was easier to just get the better version outright instead of upgrading afterwards.

Here’s the not really legal way I have heard of

1. Get a Deezer trail and cancle the sub right after. Migrate your relevant playlists to Deezer.
2. Use Deemix to download the playlist any anything you are interested in in the quality you desire. Make sure the DL settings are also what you want. You can also use other tools to download from Qobuz.
3. (Optional) Use Musicbrainz to identify and tag your files with unique IDs. You can also use custom scripts to give the artist field seperate entries for every artist. Makes it more convenient then separation by a ; or something. You can use ChatGPT for the script.
4. (Still optional) Import the music to a Lidarr instance for better management and automatic naming. The IDs make this step easier. This allows you too track new or missing releases from artists.
5. Import to Navidrome.

The optional steps can be more involved and need a lot of manual work. Also, the migration to Deezer will have issues, it’s not perfect.

If you want lyrics, I recommend using LRCGET or importing to Jellyfin and using it’s lyric plugin to automatically download them that way. The app SongSync on android also allows downloading lyrics automatically and manually from a variety is sources, including Apple and Spotify. Not on FDroid or Play, use GitHub or IzzyOnDroid.

As for a music player on android, I’m currents trying Symfonium. Not FOSS and actually paid, but so far it’s the best I have seen.

EDIT: Minor clarification.
