Give me the how

With all the new Apple announcements today I was a little disappointed, but in a different way then most. With the release of iTunes 7 Apple has finally included functionality long asked for by consumers — mainly gapless playback. On Installing the new iTunes it informed me it was ‘analyzing my library for gapless tracks’ and in their documentation is indicates that it works with mp3s etc. On the completion of the analysis, albums that I know are gapless were not indicated as such and I had to indicate it myself. Does this analysis only work with music purchased from iTunes? Also, when I made the changes for gapless my mp3 files were modified. My disappointment with Apple is a lack of explanation about how these new features work. How exactly does it make a song gapless? Can I rescan my library? Does it work with my own album rips, or only purchased songs? Sadly with their forums being down at the time of this writing I have no way to find the answers.

I’ve given up trying to find an email address at apple.com to send questions to.
