*plug* Well, we don't like MP3's anyway. Use OGG instead, this will also allow you to get rid of that "delay" at the end of the file and give you a perfectly looping tune.
And you can get smaller filesizes than MP3 at the same (audible) quality.

And there's no excuse not to use OGG anymore, it's supported by most platforms and players, even WinAmp has standard support for it! */plug*
