Hmm.. I like the all the songs in different ways so, I actually like Imaginary Friends in itself, even if it was put in a little strange place.
If I had to take out one, it would be "Say So", because I think it is just way too preachy and plain on some parts. There's even sprechtisme on one part
If I had to edit a song, it would be "Family". Now don't get me wrong, it's a great song. But the part "at the heart of every family, is loooove"; that just sounded so cheesy to me to an otherwise great song. Maybe it was just too blatantly stated?
