The latest update changed the way the ingame steam browser works, it now doesn't utilize its own built in 'browser' it now utilizes your 'default' windows browser to load the content.
The issue lies in that the ingame webpage that loads when you type !music was written mainly for IE (as thats what the ingame browser was based off)
If IE is not your default browser I suggest utilizing it.
Another option is you can simply browse to
GALORE RADIO: 24/7 Music Hits ! out of game and have it play.
Prior to doing any of this though, make sure when you type !music you wait a good 15-20 seconds for it to properly load up the browser and the page. Then, click the stream you are looking to play, and hit the play button.
Let me know if this solves your issue, if not try what I suggested above, I will look into the issue further if I can get a bit more information to help isolate the cause.
