I did some more listening, and I'll keep on sharing me experiences until someone tells me to shut the fuck up.
[t=NODE] Channel†NodeⅡ offered a very enjoyable listening. I can't pinpoint a genre for this, it's very varied, in a good way. I recommend this to everyone who likes instrumental music.
[Lapis moss] 花蝶風月: This is vocal release, and I was in fact very impressed with the opening track. It was simply a vocal song done right. The next two tracks on the other hand gave me the impression that the singer had trouble holding the tone. I don't know if it was on purpose, but it was very annoying. The last two tracks didn't suffer from that problem, but that doesn't mean they were any better. To me they sounded bland and half-assed. I'm keeping the first track and deleting the rest.
[Like a rabbit] 星の秋: Now here's a good mix of music. It starts of okay with some keyboard music. Following is up next is a vocal song, the singer isn't very upfront, she sings together with the rest of the music rather than above everything else, there's good interaction. It's a cool rock song. Luckily there's also a instrumental version of this one. Next is an instrumental track, a funky track, a piano track, and finally the instrumental ver. of the 2nd track.
[Alice Music] 東方夢乃唄～弐～: Here's some typical doujin rock. There's a good style to this, but the vocalist could have tried to make a more uniqe sound to her singing. In the end you get a little sick of it, the release lacks variety, only a few songs manages distinguish themselves from the rest.
[SOUND HOLIC feat. 709sec.] Phantom Dreamer: This is totally not my thing; it's tiering to listen to, annoying vocals and annoying guitar solos. Well, I'm no fan of Sound Holic anyway.
[Siestail] 寺へ…: I guess this is what you'll call moe or cute music. It starts out fine, the first 3 tracks, but it just gets cuter and cuter, more happy go lucky, faster, FASTER! Seriously, who enjoys this?
