I agree with kei_86... The best way to look at this is as just another genre or musical style to add to Idoling!!!'s library. If you look at Idoling!!!'s library of songs (including Shoujo Fuantei), the list of genres is quite incredible for an idol group. They are, hands-down, the most versatile idol group out there. This is one of Idoling!!!'s best aspects. Fans should be proud of it.
Now, I know this same versatility also brings a lot of unpredictability with the group's music. But personally, I really enjoy not having any idea of what Idoling!!! is gonna come out with next. I love hearing a new song and thinking, "This is Idoling!!!?" And they've been making me think that a lot recently.
To be completely honest, my favorite Idoling!!! songs in recent times have been the non-idolish songs... I mean, I love eve and Poolside Daisakusen, and Me ni wa Aoba is an incredible song to hear live, but I've been listening to the more "mainstream-sounding" songs recently. I absolutely love StarGirl★StarBoy and GO EAST!!! GO WEST!!! SGSB has those cool rapping parts, and GEGW is a great pop-ish dance tune. GEGW has already gotten the highest play count in my iTunes library, finally overtaking Shuchishin.
Now, I've never really been a fan of K-Pop. But, I've come to the realization that it's not necessarily because of the music... I actually find a lot of their tunes pretty catchy, and they get stuck in my head a lot. It's really the artists themselves and their fans that I don't really care for very much. I hate the arrogance that comes from that scene. I anticipate a lot of hate to come from K-Pop fans because of Queen Bee, especially when Idoling!!! performs it live... Ugh, I can just see the K-Pop fans nitpicking the Idoling!!! members' singing and dancing.
But, on the same note, this is a great opportunity for Idoling!!! to earn a bit of respect from the haters. If they can pull this off reasonably well, then they may actually grab a few more fans. So, I hope they bring out the decent singing and cool choreography that we all know this group is capable of.
But, bottom line for me: catchy K-Pop dance tune - arrogant artists and fans + Idoling!!! = WIN!
I can't wait to hear this whole song and see them perform it.
