I love this album! There are a lot of themes I pick up on when I listen to it, they'll probably seem pretty obvious but I shall list them anyways! XD
colour this clearly is ayu's most vibrant and colourful looking album! the entire photo-shoot from this album is very bright and colourful, the box that the CDs come in are even coloured! how awesome is that!
electricity whereas I would identify GUILTY as having a very 'gritty' theme, NEXT LEVEL, for me at least, has a very electric theme! Listening to songs like EnergizE, Sparkle and rollin' (and interludes like Disco-munication) there are a lot of sparks and digital bursts and other electronic/digital sounds (especially in Sparkle, it really should be called SPARK I feel haha!) if you check out the album art inside the booklet you will also see ayu with wires attached to her arms/hands, her hair is very frizzy in every picture (shocker!
) and the title of the album itself is wrote in a very digital-looking text...also she poses next to a lot of digital screens! also the album (particularly the songs mentioned) features quite a bit of auto-tune, giving it that further robotic feel.
GREEN I always associate the colour green with this album, I have the CD-only version so my box is green and the booklet itself with the 'a' logo on it is green...and then of course there is the amazing song GREEN, other people who have the red/blue/yellow box may not agree with me on this. (random I know but i'd count this as a 'theme' lol)
seven/7 the number seven seems to crop up a lot too, she counts to 7 in the song LOVE 'n' HATE and there is an interlude 'Pieces of SEVEN' it seems she wants us to recognise this number, some think it's symbolising the number of years she was in a relationship but I don't know about this.
overall the album is brill! it's one of my favourites, from the light j-pop DAI songs, to the electronic feel, to the extraordinary and cultural GREEN and Load of the SHUGYO, to the awesome j-rock sounds I adore, to the lovely ending ballads! a wonderful album and great themes! <3
