Hmm...lot's of great information in this thread. I think that the only reason I'd like to use OGG files at this point would be for mix discs in order to take advantage of the gapless playback mp3's come up short on. A while ago I remember reading about ripping a whole cd as one track and using specialized software that would split tracks at the 'frame' closest to the intended track split time. I couldn't find it or whatever at the time so I just accepted the teeny gaps in the playback. I know that the 'solution' mentioned here isn't an actual solution because all that is really acheived is a minimization of the gaps presence.

On a different note, would anyone care to explain how an album cover gets embedded in an mp3 and if you think it's worth the larger files sizes? I went ahead and started to embed 300x300 pixel average jpgs into all my files recently because when software that supports the feature becomes more mainstream they will be there. I use Tag&Rename to tag all my files and for some reason when I remove the album covers from the mp3s the file sizes don't decrease. Why does this occur? How do I correct this?

I have also noticed that the preferences for T&R include the option of 'writing Unicode data into ID3v2 tags' and don't know what that really means.
