You'll need the following dependencies:
- granite-7
- gstreamer-1.0
- gstreamer-pbutils-1.0
- gstreamer-tag-1.0
- gtk4

It's recommended to create a clean build environment. Run meson to configure the build environment and then ninja to build
meson build --prefix=/usr
cd build
ninja
To install, use ninja install, then execute with io.elementary.music
ninja install
io.elementary.music
