ROCK, Change the World, and Fly, Octo, Fly
This CD has:
-8 live versions of non-Off the Hook music, which are livelier, slightly-remixed versions of songs from the soundtrack. It's a nice bonus since the idols don't have that much music of their own.
-There's also 4 live Squid Sisters songs. They're very similar to the live versions for their standalone CD, which is to say that they're better sounding than the soundtrack versions. City of Color is only 55 seconds long, but the song was never actually longer: in the soundtrack, it's double the length only because it repeats. It also doesn't abruptly cut off, the song simply ends, in case you're worried--
-And, of course, all Off the Hook songs, which sound AMAZING!! I don't find most of their songs spectacular in general, but these live versions KILL IT!! Shark Bytes, Acid Hues, Fly Octo Fly and Nasty Majesty all have openings which will PUMP YOU UP for the rest of the song. Some of these added openings aren't very long but they still add a lot of energy, like on Acid Hues. Nasty Majesty is further extended with buildups throughout the song and a very nice conclusion. 90 seconds of pure ROCK is added to Muck Warfare which greatly improves the song while giving you the feeling of BENDING REALITY due to how ROCKING it is. Also, all of the songs either have proper endings or flow directly into the next song, which alone fixes the biggest problem I have with the soundtrack: the lack of proper endings.
Ebb & Flow is fine enough in the soundtrack but the live version will, at the bare minimum, fill you with ROCK due to the sheer levels of ROCK contained within this song, and it may also give you the MIGHT to TAKE ON THE WORLD, END PREJUDICE AND EVIL, purely because of how ROCKING this song is; it is a KILLER blend of squid vocals, live instruments, and EDM.
Also, there's a few tracks where the idols just talk. Sure. And the last track is a 12-minute mashup of several soundtrack songs. It's not necessary, but it doesn't hurt it, either.
Bonus points to the engineers behind this for getting a huge crowd of people to sing along to Squid music.
