Comment:
Hmm it is just 1 source file, and is simple enough that it doesn't need any updates since 2016. Here you go:
```sh
$ wget https://github.com/dasJ/spotifywm/raw/master/spotifywm.cpp
$ g++ -O3 -shared -fPIC -static-libgcc -lX11 -Wall -Wextra -DSONAME="spotifywm.so" -o spotifywm.so spotifywm.cpp
```
Packaging this just adds burden to maintain in my opinion.
