Not so fast as to negatively impact the songs (maybe even helping them in some cases, given the length of the show), at least to my recollection of my feelings. I listened to it a LOT over the 10 years from finding it to tiring of the score and only listening to the OBC when i did want to revisit it. I'd have to listen through again to weigh in fresh, as it has been several years now.
I also love having that splendid rendition of "Our Little World" there... I don't think the show needs it, and while I do love the song I think the show is long enough without it. But I'm so glad we have those two doing it in character.
