Spotify and Steam are. Although Steam doesn't really pull it off all that well.

Neither does Spotify. Visually it's out of place on every platform, and performance on computers older than few years has become unacceptable IMHO.

Spotify on Linux: clicking on things often feels slightly janky and laggy. How fitting!

And the spacebar will 80% of the time page down rather than pause the music, something which sounds minor but which makes the user experience 50% more annoying for me. Do most people even use spacebar to page down in normal webpages!?
