Didn’t click on this initially because I was sure it’d be someone getting fired for an anti-ICE comment. Nice to be pleasantly surprised.

Depends on how much music you want. I have about 3500 songs at the highest quality free YouTube will let me download songs at, and that comes to around 15GB.

but I wasn’t sure if Spotify, YouTube, or anyone else will reach out with cease and desists like has happened to me with torrents in the past

Right now Google is more focused on breaking the library that powers downloading from YouTube (yt-dlp). They haven’t succeeded yet, but that’s definitely an easier path for them than prosecuting piracy.

I doubt Spotify will try to punish you for this since the content isn’t actually being stolen from them directly.

I only use Spotify to get song/album URLs (web client search w/o login), which I then pass to spotdl to download them off YouTube. Now I have all the music I could ever want, offline and without ads.
