Imo, Duty is only good because of how they released the singles. It had the trilogy releasesl. Like Vogue ~> Far Away ~> Seasons make sense and It kinda served as the backbone for the whole album flow.
Unlike the last few albums which didn't have connectivity between the single releases. Ex. Secret's Startin/BtB... ~> Blue Bird/Beautiful Fighters??? Guilty's Glitter/Fated ~> T2M/Decision??? That's why they are more prone to interludes/preludes etc.
This album too, has no connectivity. Green/Days ~> Rule/Sparkle??? That's 4 different Genres. I don't mind the interludes, I love most of the others. Prays for something like... Judgement day, Not yet, Everlasting Dream, Catcher in the light, Taskinillusion, Neverending Dream, Starting over, opening Run, & Mirror.
I'm really looking forward the song Next Level. Even if everything else fails, the song can make up for the rest of album. I just love the preview. And oh yeah the singles are good too. ^.^
