Yes she did have a slow start; her third single, Sakuranbo, was what really put her on the map of the music industry. But I think she's great regardless. I don't know what mean by her having horrible songs, but she's a very respectful Japanese singer and amongst the elite.

Your album suggestion is a little too imposible. Everyone has a few bad songs on their albums, but you make it sound as if she only has like 1 or 2 good songs on each album and the rest are bad. She's often hated because of her, often said to have a “helium swallowed” voice, but she's just fantastic. She's has beautiful ballads like, “Planetarium”, my favourite “Kingyo Hanabi”, and “Kurage, Nagareboshi”. And also some catchy pop songs like, “Sakuranbo”, “Chu-Lip”, and “Frienger”. She's good all around(I disagree when you said she has horrible song), but only to the listeners to who can take her voice.
