Don’t like the new icon of iTunes, and find it an eyesore to look at in the dock and Front Row? Then download these icons and make your dock look pretty again.

To Install iTunes Icon:

Macintosh HD > Applications > iTunes > (right click and show package contents) > Contents > Resources

Drag and drop the ICNS file there, and click replace. Drag iTunes out of your dock and drag it back in again. Bam, you have your old iTunes 6 icon restored.

To Install Front Row Icon:

Macintosh HD > System > Library > CoreServices > Front Row (right click and show package contents) > Contents > Resources

Drag and drop the PNG there. Then open Activity Monitor and quit FrontRow. Next time you open Front Row you will have the old icon restored.
