Yeh Ayu's ballads are pretty similar, but I don't get bored of them. They get better and better for me each time. However I started being a fan of Ayu about 4 years ago, so I've only really been following her songs since 2006. So I can understand if people are starting to get bored of her songs
I don't understand why bands such as AKB48 and KAT-TUN sell like 300,000 - 500,000 in a week
