I never voted on one of these ever.
...this should be fun.
ffmqbattle - This has good instrumentation and good mixing. The pitch bends sound so nice and satisfying, especially on some of the parts where it slides down right at the end of the note. Nice work!
sonic2sms_-_skyhigh - Now this is groovy. That bass is a 11/10, and it sounds great with the other samples, which were part of the requirement. I'm more for the electric piano sample, but the square wave is a good fit here too.
nutshack remix - That's clever actually. You have sweeping effects going on (er... two channels that seem to be playing the same exact thing, except one is slightly detuned. That's sweeping right?). Whole thing seems well polished. The percussion is kind of weird to me, but eh, this is overall meant to be weird I think.
honnou - Wow, someone actually used the Distortion Guitar.brr? Surprised honestly. I don't hear it though. Anyways, this is neat. I really like how the chords sound here, especially in the intro. One thing though: is it me or does that intro not match up at all with the verse immediately after it? Mixing could be improved with some panning and perhaps lowering the volume of the lead instrument (it's kinda loud).
gimmick_happy_birthday - This sounds cute and I kinda like it. Though, this seems like it's on the simple side of things. I think this could sound a little better with some panning. I'd remove the reverb from the bass and give it no release. Also the drum beat is sorta lacking a bass kick. I know you're using @21, but it is just not good enough for this song.
1989 - This is alright. Loving the sound of the slap bass here especially considering what the theme of this challenge is. However, I'm not really a fan of how SMW samples are clashing with that slap bass sample.
sor2_expander - The beat of this and the chords are nice, and the panning effects are cool. Unfortunately, that's the only good I'm getting out of this. Mixing is off, and the quiet bass isn't doing any favors. The sample quality is all over the place to me. The one sample at the start of the song seems to have clicking which is bad. The lead notation is just... a raging flurry of pins and needles. Is that actually a part of the original song?
9party - Oh, I know this song. It's a cool song, but the lack of custom ADSR on those vanilla samples are making this sound too bland. Even then, I can't stand the @8s for the bass synths, or the uses of the @5s towards the end. Kinda disappointed.
Blast Hornet - Eh, the volume mixing is bad. I get blasted in the ears with a random white noise for less than a second about 20 or so times in this song and it's so out of place and irritating. @17 is one of those risky samples to use. It ruins the entire song if used wrong, and sadly, I'm leaning towards "it was used wrong" here. Sorry, but it sounds really silly when it goes to high pitched notes.
drwily3 - The snare is way too quiet, and I think the timing is off on some of your channels. Major issue: It's missing the bass (including the bass drum). That alone is enough to make this sound empty. It's really headache inducing when all I'm listing to is just the whirling high pitched notes all over the place.
