Show current track

[brantlk]

Would be nice if the app monitored the system to see what track is playing and send that to the cast device. I'm using Amarok on Kubuntu.

[muammar]

I was thinking of implementing something like that, but the big problem would be to have a standard way of getting name's song from popular music players. An example with Spotify installed with snap on Debian unstable:
