^ I guess there aren't many radio edits in the J-Pop world because Japanese songs are expected to be a few minutes longer on average than, say, in the U.S., and it's hard to be too long (a song is rarely cut for anything, other than a music show that would be strapped for time). In the U.S., on the other hand, a song is considered pretty long if it's about four minutes or more, so I can see why they'd make a radio edit of such a 'long' song. (Another stand-out different between the two music industries.)

I honestly don't know why this would be a radio rip, cut like this.... Maybe, but I can't remember a time when I heard of a song being cut for radio, except for obvious remixes.
....I honestly have no clue why we're missing a verse in this preview, lol. But I'm sure we'll find out for sure soon.
