RAS benefits so much from having a DJ in the band, turning what would normally be something somewhere between Afterglow's rockier stuff and Roselia's louder things into something new entirely with a unique identity and those kiCK-ASS dubstep-y parts
since the only other band with a DJ is HaroHapi and they have an entirely different style & musical identity, RAS can do things none of the other bands can and they make the most of it. their songs would be good without it, but the fact that they can play around with a much more electronic sound without it ever being too much and losing the natural sound of, well, a full band, makes them all the greater
they also sound very much less "anime"/"idol-y" (in lack of a better word) than the other bands which makes sense since while they do now have anime counterparts, they're a live band first and foremost. if they weren't tied to a mainly 2D franchise at all there wouldn't be any difference in their sound if that makes sense
also Raychell has the absolute best singing voice in all of BanDori imo, and the other girls already sound amazing
this is really just a RAS appreciation post, with their first single out now I hope they're gonna be just as successful as the rest of BanDori because they absolutely deserve it
