CoverScout from equinux is a great piece of software helping you for small money to get your iTunes library tuned and optimized. First this software helps you to get covers from different sources: amazon.com, google.com etc. Furthermore it ensure that the cover pictures are stored in EVERY file. iTunes itself stores the pictures in a way, which is quite difficult do understand, not to say more. You can realize this if you want to use your pictures with different media (e.g. your car, other DVD mp3 players, hardware as the Sonos Digital Music System.

Ensuring manually that all pictures are stored in each file is not only a question of time. If you have more than one thousand entries in your iTunes library, I swear you can just forget to get 100% quality by trying to do it on your own. Although in case you would achieve accuracy in this task, it will mean that you spend just too much time on ot.

For less than 30 bucks, CoverScout helps you to achieve this task smoothly and even with fun. the grafical user interface is great and myself being a developer or having worked as developer I believe the price is really modest as this small piece of software works as charm.
