I ditched Spotify and set up my own music stack

Wow, that’s a lot. Just install any offline music player on your phone and transfer songs to it…?

My current music collection is 399GB (mostly lossless Flacs).

I'm not buying a phone with 512GB-1TB of storage just for my music, 5G is available everywhere and my home internet connection is plenty fast. I can just stream it from home - maybe sync some locally if I'm going off grid.

And moving files manually one by one to my phone? Oof. It's not the early 2000s, we have better solutions.

Or the middle way, just install one of {navidrome/plex/jellyfin} + app.

But OPs stack also can do a bit more.

My music collection would not fit on my phone. But I got 1Gbit/s upload and 4G connection most of the time.

>I'm not buying a phone with 512GB-1TB of storage just for my music,

If a 512GB phone costs you $300 dollar more tahn the one you would have bought, it amounts to $2 per month for a 5-year phone. Spotify is three times that.

$300 will also get me a used mini PC[0] with 2TB of storage[1] I can set up at home in an evening with Navidrome+Audiobookshelf and not have to buy a phone with massive storage at all! :D

And as a bonus everyone in my family can listen to the same collection without having to upgrade to a 1TB phone. And I can use the same source in my car, on my laptop, desktop etc. All without having to waste 400GB of space for music storage on every device.

Then convert it to Opus. I have a similar ~440 GB in FLAC and would never opt for such a complex solution when one of the major benefits of FLAC is that you can do proper encoding yourself.

I mean, you’ll never listen to 399 GB of music at the same time. So, not really an issue.
