I've been waiting forever for a Chrome extension that shows which tab is playing music. I wonder if that's even possible. Part of the research I do online requires me to go to several sites including those who, for some dumb reason, think it's alright to hide the music player. If I want to listen to music I can play my own and I usually am listening to something else when a random site starts playing random looped songs.
The answer doesn't have to refer to a Chrome extension, even though I'd preffer, but if anything can detect - maybe even mute - random songs I'd use another browser for that.
