Why is First Love the highest selling album?

[bluegie]

All I can say is.. if First Love wasn't that success, there would be no hikki. Then again, there must be something about hikki that makes many people love her. I just dun think hiding from the public would continue the success.
Remember Mai Kuraki? She's the "clone" of hikki, as her company used the same tactic to sell her: 1) hiding her, 2) R&B pop, 3)quite talent (writing her own lyrics). She was a bit thing in 2000. I remember that I hated her so much because she technically copied hikki's moves, but I ended up liking her songs as well (R&B-pop, the popular type at that moment) (PS: I was a bit sad when Duty couldn't sell more than Delicious Way.. I thought Duty would break 2 million copies on the first week, but ended up selling around 1.68 (?) million copies..).

Anywayz, Mai could not maintain her popularity and sank gradually (like... from yearly no. 1 album selling artist to selling less than a million copies for her second album. It was quite a drop). Her songs became too generic in the end. I guess that makes the difference between hikki and mai. Hikki did create a even more generic album after First Love (yeah.. I think Distance is her worst album even tho the singles are great). But then she began to seek for new direction and DR was the OMG album from her.
