[PROBLEM] V4.4 Spotify - track selection problems

[new_bloke]

I build librespot using docker - it takes about 15 minutes in total, including building the image, and then compiling the binaries. Could this be extended to produce a Pi Zero version? Cross-compiling isn't something I know very much about.

Once I have the binary, is it a simple case of copying it over the top of the existing one in the moode setup? Or is there more to it than that?
