The title track is tacky and cheap? Yeah kinda but their debut album & stages are really good!
My personal favourite in the album is Another Dream, all those backing harmonizations reminds me so much of SNSD sounds and I actually loves it. All girls sings well(even Hiyyih)
Personally, I think the trouble I have with Wa Da Da is how unbalanced it is and it is expected - how can you give them a girl-crush-cutesy concept when the best rapper in the group is not ready? If Hikaru can showcases her rap skills I'm pretty sure the song would've been much better.
Judging on their debut stages, it just feels approriate for them to go down the two legendary 9 member GG route - rock off cute-teenage concept in their debut years.
SHINE really serves justice for Kep1er and I think it's best for them to comeback with this kind of song - upbeat high-school vibes. Also I can finally see all 9 member PRESENT on stage as opposed to just some grabbing all the screentime in Wa Da Da
