Again can't read the whole translation, will do so later when forumotion (grrr $^ù#~!) is working again... but this talk about special songs makes me crazy, so much hope for some songs... :D
Well I don't think the songs from STANDARD fall into this category, surely they do no think of
8gatsu or METRONOME as songs they just want to play once and then be done with. And they played them before anyway. Still hope they will play them, obviously they will not play only "special songs", they will do a mix.
They could play songs they have never played at a live before :
https://www.scandal-heaven.com/t10437-songs-never-played-live-or-on-tv For example,
Sunny Day Sunday, Midnight Television, How Crazy or SCANDAL IN THE HOUSE. The list is not that long ^^
They could also come up with one or several new cover songs they want to play for just that live. They do that sometimes for some concerts like
Garasu no Shounen at BEST Xmas 5. I actually think there is a good chance they do at least one song like that.
But what I really hope are songs that they just simply never played on TV, and here the list is much longer!
Well if I could only choose one song it would be
SCANDAL IN THE HOUSE. I have the feeling that an arena is probably the only chance to see that song, I can't imagine them playing that song elsewhere or at least on TV. They might play it during a normal concert yeah but on TV they will surely not play it at a festival, it's basically a pure fan service crazy song ^^
If they play it on TV I forgive them for the 360° no-DVD =P
