I used to use this functionality (Steam Music Player) all the time without issue both inside and outside of a game.

After a recent update however(1-2month I would say), there is no more hope it seems. It has a tendency to crash whenever I pick a new song from my library. It will load for a few seconds,then it will close steam. If I pick a different song after restarting, it might resolve temporarily. But after a few minutes, high chance that it will go straight back to crashing if it gets in a "bad mood" so to speak.

Does anyone else have this? Is something wrong with the way I have mine set up? Why is this happening?
