I may be a huge Vocaloid fan, but I'm definitely slow on the draw with this album as it took me a while to actually listen to the songs on this CD. But I'm glad that I bought this as it's truly a great album and I'd say a collector's item for Vocaloid fans as this was the first commercially sold Vocaloid album, even before another famous Vocaloid composer Ryo aka Supercell. Heck, even the box is beautiful, the art was done by Redjuice, a well known artist when it comes to doing Vocaloid art as figures have been made of his pictures of Miku.
The genre this falls under in techno/pop(My iTunes says electronica/dance but it's basically the same.), which is the genre Miku is best suited for in my opinion.(Of course you'll find her covering almost all genres on the internet.) There's quite a few slow songs and some really catchy, quiker songs that always makes me want to dance. The songs Packaged, Last Night, Good Night, and Strobo Nights were also featured in Miku's first game, Hatsune Miku Project Diva, which I also own. Another song on this album, Finder, was featured in the sequel to it, Project Diva 2nd but remixed.
KZ, the composer, definitely has a unique style when using Miku, like most Vocaloid composers, as he(actually I don't know KZ's gender...) sets her to a higher pitch(Last Night, Good Night for example is so high I thought for a while no human could sing it until I saw fan-made covers of it.) and the songs themselves have a very nice techno/pop feel no matter what song it is. It's hard for me to pick a favorite song but I'll note the ones I like listening to the most. Anthem, the first track, has a really good dance feel to it to me and I really like how slow it starts out and has a "fuzzy" like sound in it. Packaged of course is the iconic song for this album and like many Vocaloid fans I love it and how it has such an upbeat feel. Light Song and Finder I have almost the same opinion on, both have a very nice pop feel to them. Strobo Nights and Last Night, Good Night I'd say could be my favorites, Strobo Nights is easily just as famous as Packaged and I love Last Night, Good Night because of its slow, dream-like feel to it. Couple that with Miku's voice and the translation to the lyrics, this is the song that made me fall for Miku in the first place. Track 6, which I don't know the title name because it's written in kanji that I can't read, I'd also like to note as I love it too. Mainly because it sounds like traditional Japanese music, it makes me think like it should be played at a Japanese festival.
To finish things up, this, like many other Vocaloid albums, any Vocaloid fan should get and add to their collection of songs.
