On the iTunes page, it said 5:22, I noticed it as well, maybe it's hinting at a May 22nd release? This date is a Wednesday, meaning something could potentially could come out. I noticed that 2 of those tracks were made with the help of AOKI takamasa. If it is something significant, maybe they'll have a project together. Also since they were instrumental tracks, it would have been much easier to intentionally make them that exact length. The only other track with this duration is Music. It seems likely that Yamaguchi would do something clever like this, his friend Koide Yusuke, (frontman of BaseBallBear) once used the line 0902 in a song released in Jaunary and they released an album later that year on September 2nd.
Wait, what if you played the songs simultaneously?
Maybe they become a new track.
The reversible cover represents the sides of a coin, it makes sense now, considering how the album is dance songs on "heads" and more laid back songs on "tails"
I think they made it really experimental because they had so many free spaces for tracks. I'm actually happy about the direction, because their increased popularity and presence in popular culture (the dramas and tie ins) gave me the impression that they would have to change to something more conventional, but this isn't the case! They debuted #1 on Oricon
while keeping their experimental side.
With only a few singles on it, they could make the songs that are supposed to grab you immediately, get really creative with some of the others, while cohesively putting the bulk of the album together with only one deadline in mind. It was very electronic this time, Aoi is the only song with rock guitar presence. I was shocked by that move. It almost makes me wish that I didn't hear the track ahead of time, it would have been nicer as a surprise. Also, I wonder how they'll play these live, for example, will Ami be on her synth keyboard instead of bass for more tracks, or will they give the songs more of a rock band sound when they are performed. What about Iwadera... Will they work an actual guitar into these? Maybe he'll just use pedals to add to the dance music sound.
I was impressed by the distinct way a lot of the songs were sung. (The syllables in Nantettatte Haru's chorus, Aldebaran's repetition, or Aoi's repetition of certain words in the chorus, the bounciness of M, the really continuous part of Boil
that made Yamaguchi lose his breath, the smoothness of Mellow's last choruses.)
It seemed very well balanced and they placed the singles in the best spots as far as where they would make sense for the flow of the album. M seems like an Arabian cousin of Yoru no Odoriko, the way it's sung also makes me think of Omotesando 26ji, not only the Emi part, Yamaguchi as well. Why is it called M? I didn't notice anything in the lyrics that revealed it. I enjoyed INORI more than I expected, and Mellow has a nice conclusion. I really liked tracks 5 through 9 the most. Nantettatte Haru & Aldebaran are so cool, I hope they try more songs like these, and they are perfect leading up to M. Boil is beautiful! They really improved Eiga with the proper ending, I knew it was going to be a revisit of Music's B-side, it just seemed too much like a teaser for something to come up later. Structure is an interesting track, it's like a folk guitar and someone puts on a 90s hip hop beat, and then later it turns into a hold hands around the world for peace song.
I was hoping that they would put some surprise twist in Asa no Uta, but it was a nice ending just the same. I'm excited for the Bach remix, I will try to wait until my copy arrives. From what I've seen online, hardly anyone in the English speaking fanbase has heard it. I think it's because of the worldwide iTunes release being the main source of the album that is being distributed, since it wasn't included there.
