I'm using these versions

• Windows version: 10
• Dopamine version: 2.0p6

Reproduction steps

• Play a song

Observed behavior

Dopamine has small spectrum analyser animation next to playing song, which is difficult to notice

Desired behavior

Dopamine should add more visual indication for which song is playing, perhaps change text/background color of currently playing song or more animations
