^Yeap, this song...^^ Ayu also covered one of her songs for A Ballads =) (the japanese titled one she sang at CDL 07-08)
@TeamAyu2004 Ayu was huge 10 years ago... But if she wasn't big enough today, not even the best catalog would put her on the list^~ Koda is more recent, has as many songs as Ayu and still, Ayu did better.
Considering Jpop pattern of releasing, her discography is not big, just average, BTW. The outstanding think about her was being able to produce so many hits
About Matsutoya Yumi, she is regarded as one of Japan's biggest popstars, singer-songwritters and performers, and also the 2nd best selling female singer (behind Ayu). She is around since the 70s and still is able to sell out 70+ dates tours^^. You can her influences from her on a lot of stuff people like Ayu and Hikki did.
