I've been quite busy this week, so I haven't played the files as much as I'd like. A few quick comments, I MIGHT post more in-depth comments later:
-24/7 basically was Shades of Gray done right. Loved it.
-Addicted to Bass was COOL, superb chart. Wish that mp3 was a bit louder, because when I scroll to the next song it's SO loud lol
-Astrogation was great but it seems to go offsync late in the song, incorrect bpm?
-I liked birthday expert, but the challenge chart was quite overdone. I didn't expected to like it when I heard the sample, honestly.
-Colorful Cookie was vainilla plain. This would have been so awesome...in 2004. It wasn't bad by any means, it's just that I've played so many charts like this that it's not exciting anymore.
-Discotheque was quite above average for an anime simfile, very fun to play. Didn't felt like you had to like the anime to appreciate the simfile unlike the ones in Bracket 1.
-Gee is such an awesome song, but I think the stepchart does not makes justice to the song. It's kinda on the safe side really, you could have done so much more many interesting patterns with freezes. It still was cool.
-I don't get all the hate Konamized is getting, I thought it was pretty neat except for that it feels offsync late in the song. Seems like another incorrect bpm case. The presentation was quite poor though (banner and bg), the videos you used saved it in this area, luckily.
-Livin in the sunlight etc honestly scared me. It was quite fun though, good job handling that drifting bpm. At some points I think you should have used 12th notes instead of 8ths.
-Revolution was also pretty bland, but not colorful cookie-bland. Steps were ok but they did nothing outstanding for me.
-Sonic Speed Riders was surprisingly good. I think it's safe to assume this passes to the next round.
-The sugar polka etc song was excellently done, good combination of playability and lol-factor.
-I liked Umineko at first, but I it was way too long for my tastes, it should have ended much earlier I think.
-China Discotica is probably my favorite in this bracket, but there are lots of good files here. This was so good, although I think it should be a 7, not a 6 footer.
-negai was surprisingly boring for a perfume song, as much as I love them. I almost felt asleep midsong
