iTunes adds "Complete my album"

Apple has added a new "Complete My Album" feature to iTunes Music Store. This feature searches for individual tracks that you've already bought through the service and sees which ones you haven't bought the full albums for yet. It then displays all of the albums that you can complete, and for what price.

Apple will allow you to buy the remainder of any album from which you've purchased one or more songs at a supposedly reduced* price for up to 6 months. Apple is giving users a grace period until June 26, 2007 for previous purchases.

* These don't look like 'reduced' prices to me. All of the listed albums are offered above the regular price of $9.99.
