You may be familiar with the iTunes Mini Player window. When you’re playing music, and click the green button at the top-left of the iTunes window, the Mini Player window displays, offering you basic controls for your music.
iTunes 10 added another type of “mini player,” which I’ll call the “artwork player.” When listening to music in iTunes, display the music’s artwork by clicking the artwork viewer button, the fourth button from the left at the bottom of the Itunes window . Click on the artwork, and it will display in its own window. If you hover over this window, you’ll see that there are controllers visible. (These are the same type of controllers you can see when playing videos in iTunes, or in QuickTime Player.)
Now, you can minimize the main iTunes window by clicking the yellow button in the top-left corner, and use this window to control your playback.
If you’re listening to a single album, the artwork will remain the same; if you’re listening to a playlist of songs from different albums, the artwork will change as the songs change. If what you want to listen to has no artwork, you can still use this window: it will display two musical notes. You can resize the window by dragging the bottom-right corner, so you can make it very small if you want. It doesn’t, however, give you the option to have it float over other windows as the Mini Player does.
