searchme, sock marks, you guys are delusional. First of all she needs singles to promote albums, without them she is sure to sell less. And secondly what oversaturation are we talking about? She's been release like crazy since 12 singles project. Actually scrap that, she was releasing singles like every 2 months starting with 'feel my mind'.
Mini-albums can be good and enjoyable, but avex probably wouldn't release them with Kuu, because the production costs would be higher while she more likely sell the same. In the end it doesn't matter what format it released, what matters is the music itself.
