@jonaski That's what I thought, too, though it doesn't work in Clementine, either, and hasn't for a couple of Ubuntu versions. I haven't been able to get it to work in Strawberry at all, either by stopping with a song playing and then restarting Strawberry, starting it from the command line with various options including loading a playlist, or using Startup Applications.

I gave up and I'm using Quod Libet.
