You can control your music at anytime with the shortcuts. They are usable system-wide, even if the window is not visible. They are of course fully rebindable.
Embedding a Snapcast client allows to listen to music on multiple devices. For example, if you music is on a distant server connected to speakers in your living room, you can still listen to it on your computer running unison with this integrated client.
Through [Radio-Browser](https://www.radio-browser.info), a community database, you can play radio streams directly from unison. There are more than 28,000 stations recorded on this service, so it is a nice way to discover new music and cultures.
