CDTV's top 10 total weeks for singles at #1 (Ayu is #1)

[truehappiness]

Keep in mind that some Ayu singles did get #1 for more than one week which is why she coincidentally has the same number of singles at the moment as weeks at #1. It's a bit odd though since some artists have more actual #1s than singles (Masaharu Fukuyama has more than 22 but for some reason they're not accounted for here...)

01. あゆ 50週 Ayumi Hamasaki - 50 weeks
02. B'z 48週 - 48 weeks
03. Mr.Children 45週 - 45 weeks
04. Kinki Kids 42週 - 42 weeks
05. SMAP 33週 - 33 weeks
06. 嵐 32週 ARASHI - 32 weeks
07..GLAY 30週 - 30 weeks
08. 宇多田ﾋｶﾙ 25週 Utada Hikaru - 25 weeks
09. ﾗﾙｸ･ｱﾝ･ｼｴﾙ 22週 L'arc en Ciel - 22 weeks　
09. V6 22週 - 22 weeks
09. 福山雅治 22週 Fukuyama Masaharu - 22 weeks

B'z is really coming close to Ayu's total.
