That seems expensive. Are you storing your FLACs in AWS Glacier? If so, you're doing it wrong.

e.g. mine are in a well backed up filesystem, reachable from anywhere in the world via my tailscale network.

Typically mounted read-only on whatever computer I am using, at definitely less than $12/mo.

In contrast, Spotify doesn't even have much of the music I listen to.
