50GB of flac = maybe 20GB of Vorbis amirite? Is that 450GB of flac in your screen shot? It would fit on a 256gb phone even without an SD card. A 512GB card is quite affordable these days. Just make sure to buy a phone with a slot, and think of it as next level degoogling ;).

Yeah I know there’s lots of music in the world but who wants to listen to all of it on a moment’s notice anyway?
