Goodbye Baby- question about the audio quality

[bwboy]

Something I've always wondered about is Goodbye Baby on Say You Will- the quality seems very bad in the beginning, almost like a demo rather than a fully produced track. I am not an expert when it comes to terms like 'remastered' or whatever, so for me to notice something about the poor audio quality means it has to be pretty noticeable. I can't believe they just threw the demo on the album, but why does it sound that way?

Anyone else notice what I'm talking about?
