Hi guys! Here I'm just going to share my 100% honest opinion about the new singles since all 6 bands have released theirs for season 3! This is going to be long so get ready!
Poppin' Party

Um ngl the new theme song made me cry. Enough said.
#jk you thot
So yeah, the new Popipa sound and actually the new sound of all of the bands are I N C R E D I B L E. I loved the passion and emotion conveyed by Popipa. It reminded me of Teardrops (like the only other song that is in a minor key). Yeah it made me cry, and I don't even speak Japanese so that was kind of amazing how well Popipa can convey emotion. Wow, stan Popipa 4 lyfe.
Afterglow

Ok I think their glam up took over the internet more than Baby Yoda so I'll just leave it at Himari best girl. I feel like Easy Come Easy Go is a nod to the original Afterglow sound, and I really like how the different members got a solo (HIMARI HAS A DOKIDOKI VOICE). But いつ戻りのBrand New Days was amazing. It actually in the beginning reminded me of like a really weird mix of original Afterglow, Pasupare, and Popipa. Anyway, their new sound is AMAZING and needs to get recognized for its greatness. The drums were toned down a bit (NO SHADE TOMOE) and keyboard got more of a voice, which I liked.
Pastel*Palettes

Again beautiful album cover; ofc Maya is left out as usual, and Hina is reaching for my wig about to snatch it. Wakuwaku meets Torippu was interesting... not like anything I have ever heard from the band. It's a bop none the less, especially with every girl getting her solo. Nothing beats Kyu~MaiFlower, but still it was weird. But then Gyuu days was much more of a bop. I liked the trumpet and glockenspiel percussion that paid homage to ShuwarinDreamin. It was really cute and felt more like Pasupare, but I still feel like the band is going a bit away from the iconic style that I really liked.
Roselia

Again I have to say, the first album song Yakusoku was just not doing it for me. It felt like the original gothic, church bell Roselia with Black Shout that I didn't enjoy that much; I wish they had gone off of their new style found in the latest albums. "UNIONS" Road was pretty good; I liked the sound of it. I'm still searching for that upbeat, intense passion I found in Fire Bird, Ringing Bloom, and Neo-Aspect.
Hello, Happy World!

I think this was really the only band who actually stayed true to the sound they created with their season 2 single. Always a pleaser. I love the new police costumes and the songs are fun. Not much to say just Haro Hapi doin' their thing to make the whole world smile. I'm proud to actually hear the guitar and bass, whereas it used to basically be Misaki and Kokoro as all I could hear (with a hint of Kanon).
RAISE A SUILEN

Omg I cannot believe the transformation of this band. They went from being a backup band to being the best band. Yes, unpopular opinion, but it's true. Think about RIOT; it sounded like bad dub step. Now, their music is filled with emotion and is raw yet is still both electronic and electrifying. Their music is filled with passion and intensity that inspires me. The complexity of Drive Us Crazy is unprecedented and honestly makes the other bands look bad. Same with Hell! or Hell? which showed off Chu2's amazing DJ and rapping skills. Layer has a very rich and luscious voice that sets the band apart. Can we just give Lock an award for all of her right hand fretting, plz??? And Chu2 rapping gives me life (Kokoro has been dethroned, yes). It's time that RAISE A SUILEN gets added to Girls Band Party. It's been long enough. They have enough songs and they deserve the recognition that their music equivocates.
Anyway, after that long rant, you can see my thoughts. Thanks for reading! Stay fleeting! Happy Christmas, Chanukah, Kwanzaa, etc.
