The one in which you control iTunes with keywords
With the 0.9 updates to the Powerpack, it’s gotten even easier to control your iTunes music library and navigate to the best music.
Whether you are in the main Alfred window or inside the iTunes Mini Player, you can now use keywords to play or pause the currently playing song, select next or previous track or play a random album. With keywords you can also quickly and easily toggle volume to maximum, half or completely mute your music.
You can customise these keywords in Preferences > Features > iTunes > Keywords.
