Volumio doesn’t include Spotify as a built‑in native service, but it does support it through the official Spotify plugin, which is maintained by the Volumio community. It uses Librespot under the hood, so you get full Spotify Connect functionality and in‑app browsing. It’s not an “unofficial hack”, it’s simply implemented via Librespot rather than Spotify’s closed SDK.
As we speak Volumio is in contact with Spotify, which will hopefully result in a closed SDK.
