To be perfectly honest to oomf, I didn't think I'd be a big fan of the vocaloid stuff. (not sure why) I will say though, this album is very familiar to the stuff my brother would listen to a lot when I was younger with a twist of Japanese in the mix. It actually brings up a lot of memory of when I had his Xperia PLAY with his SD card still there and I had all of his music on there, probably the first time I had ever listened to a full song of my own volition (not on the radio or whatever).
Reon - Remind reallllyyy stood out to me. It starts with something so smooth and calm, goes into metal, then goes into Rock? It's such an interesting song, I actually fuck with it sooo heavy.
I have no idea what the songs are actually about, I don't know Japanese and I think part of a song's charm is being able to hear the emotion behind a specific lyric in the moment. I know though that there's probably some insane lore that intersects a bunch of other stuff, idk. It's got a great couple of songs though. I really enjoyed listening to this.
