Yes, you should have right. In my opinion, Suara's voice is great for ballads. The Karin album is not so bad, but I miss those kind of true ballads, which were on Yumeji (Toki no Kawa, Kimi ga Tame, MOON PHASE) or on Kizuna (Shunkashuutou, Hana Kotoba). On these songs, I hear her inner heart, and these touch me very much. Her commercial songs are really not so good, the fast songs, like Free and Dream is quite good, but not her style. If somebody wants to hear her true talented voice, give a try to her ballads on her albums.
She's never been great anyway. Let's face it, a few songs stand out but most of them are just common anime crap. Sucks because Suara's voice is really sweet and unlike most J-poppers, she can actually sing. Also, the traditional/folkish influence should be more developed, seems to be her trademark so she should stick to it instead of switching to more commercial songs. She has potential but in albums like Karin it's utterly wasted.
