By midafternoon, I usually have so many tabs open, I can't keep track of them all. It's really a nuisance when I have music playing on one of my many tabs and can't locate it quickly to mute the song that's playing to answer the phone. Enter Music Controller, a Chrome extension that adds a button to the right of your URL bar. The button, which features a music note, provides access to any song currently playing on any tab in your current Chrome window.
Music Controller claims to work with Google Music, Grooveshark, Mog, Rdio, Pandora, and YouTube. Using a Mac, I could not get it to work with Google Music. And it recognized Rdio but failed to list any tracks played with that service. For the others, however, it worked as advertised. Click on the button to open a small window that lists any song (with artist info) currently playing or paused in any of the above services. Next to each song listed is a pause button and, if you are listening to a playlist, fast-forward and rewind buttons. Thumbs-up and -down buttons are present if the music service has a rating system. A mute button at the top lets you quickly mute any song playing, and if you click on a song, you'll be taken to the tab where that song is playing.
