Most solos that "don't fit" are usually just an unusual choice. It still grows on repeated listens though.
The Carpenters solo threw me at first. I still don't feel like it was the way it was intended to be. It sounds like they just plugged straight into the console to get that fuzz sound, but a glossier sound would have made it feel a little more unified with the rest of the song. I've still gotten used to the solo, so it doesn't strike me as being too weird.
