In my explorations of the intertubes, I’ve found quite a cool hidden feature in iTunes. As shown in the image above, with a simple Terminal command, you can make iTunes’ dock icon have a little bubble above it with the name and artist of the current song. This bubble is shown whenever a new song begins.
To enable this, quit iTunes, and launch Terminal (located at /Applications/Utilities/Terminal.app). At the command line, paste in the following, and press the return key:
defaults write com.apple.dock itunes-notifications -bool TRUE;killall Dock
The dock will disappear for a couple of seconds, and then come back. Now, you’ll magically be notified of the name and artist of each song.
If you decide that you don’t like having these alerts, just repeat the steps above, and in the command, change the word “TRUE” to “FALSE”
