Well, his length-of-time-as-Ayu-composer to amount of songs on album = RIDICULOUS.

He started in 2003 with ANGEL'S SONG and Memorial address, so let's count from there.

2003: ANGEL'S SONG, Memorial address for a total of 2.
2004: HOPE or PAIN, HAPPY ENDING, Moments, walking proud, INSPIRE, HONEY, for a total of 6.
2005: (miss)understood for a total of 1 [OMG BEST YEAR? XD]
2006: JEWEL, momentum, kiss o' kill, Secret for a total of 4
2007: part of Me, (don't) Leave me alone, GUILTY, MY ALL for a total of 4.

That's 17 songs in around 5 years with Ayu. Average of around 3 - 4 songs per year. WHY DOES HE GET TREATED SO WELL? D: lol

Let's analyze DAI for the heck of it. [with CREAs and others are counted]
1999: Fly high, Trauma, Boys & Girls, TO BE, end roll, too late for a total of 6.
2000: Far away, AUDIENCE, SEASONS, teddy bear for a total of 4.
2001: Daybreak, Dearest, no more words, flower garden for a total of 4.
2002: WE WISH, Real me, Free&Easy, HANABI, July 1st, Voyage, independent, + for a total of 8.

2004: NONE.
2005: Will for a total of 1.
2006: BLUE BIRD for a total of 1.

This adds up to 27 songs divided by 9 years with Ayu.. around 3 songs a year. :<
