I'm also interested in your reasons, zeroryouko!
You guys have named some songs (like kaitei ni sukuu otoko, and totta teguchi) that I can't really remember but would probably not skip in the context of their albums.
I agree on gips; it's personally draining for me for some reason, and really does slow down the album's momentum. I kind of sigh when it pops into live sets too...oops...
though if I hear it come on while I'm out and about (it's happened a few times) then I'm suddenly really into it and ready to shout along
