JustLookin' allows you to bookmark music that you're interested in, on the Apple iTunes Music Store. The iTunes music store provides you with a great way to find new music. Saving just the URL's to the iTMS isn't descriptive enough, the shopping cart is not for saving for later especially if you want to buy some but for other items you're JustLookin'.
Version 1.1 adds HTML exporting.
Mac OS X 10.2 or later, iTunes 4.x, BSD Subsystem (installed by default).
