On Linux, check out Nuvola player (https://github.com/tiliado/nuvolaplayer) - it basically wraps the web UI and provides integration with global media keys / shortcuts and the underlying sound menu (in Ubuntu). As a plus, it integrates with other cloud music streaming services too.

There's also Tomahawk (https://www.tomahawk-player.org/) but I found it a bit too buggy, and unable to canonicalize songs across the streaming music providers.
