raspotify VS libspotify-archive

Basically Raspotify but for windows.

If you have a raspberry pi, Raspotify works pretty great as a Connect receiver with a little tinkering.

Raspotify installed on a raspberry pi would be my recommendation. Config allows you to normalise volume controls - have a read here: https://github.com/dtcooper/raspotify/wiki/Configuration

The last.fm site will work independently from airplay, so it will display whatever is playing, even if you are not using airplay to stream to your pi. Because it is just a standard Raspberry Pi OS running, you could also set it up as a MPD client https://linuxhint.com/raspberry-pi-music-station-mpd/ or https://github.com/dtcooper/raspotify. As long as you are submitting music to last.fm the song will display.

I have previously used raspotify on my 3B+, is there any way to achieve something similar on a pico?

For Spotify Connect on a Pi I can recommend Raspotify:

https://github.com/dtcooper/raspotify allows you to use Spotify connect on Raspberry Pi's, so you can manually move your music using the Spotify app.

The integration of Spotify, the great daddy of audio streamers with third-party apps has been difficult over the years. Years ago, in their beginning they liberated libspotify, coded in for integration with different clients. Integration with major audio players like Foobar, Clementine and MusicBee were working, but in 2015 the company decided to drop the new development on the library and decided to shut down the integration last June. The new feature called Spotify Connect that allows multiple device to act as remote controller for the device that its playing in real time made new possibilities. But the wheel was inventend with LibReSpot, a library written in Rust. More libraries ported from the original in Rust appeared later in Go and Java. This last one is special, since it allows to be controlled by HTTP requests and interacts with a potential client through WebSockets. So a good player is possible to be built through a GUI library, and so I picked the most user friendly GUI framework, PySimpleGUI, that wraps multiple and more complex GUI frameworks like Tkinter and PyQT providing easyness of development.

Others have been suggesting Libspotify still works for legacy embedded device reasons... https://github.com/mopidy/libspotify-archive seems to have Android and iOS builds.
