What Japanese song(s) are you so addicted to you still listen to them?

It has been Ayumi Hamasaki since 2003..Her music help me throughout my teenhood / adulthood years. Although her music slowly declining these past few years, I kept on listening to her...

"Endless Sorrow -Original Version- " usually makes me teary whenever I'm watching the PV. "Fairyland" and "BLUE BIRD" often reminds me of my teen years.  "meaning of Love" &  "Because of You" would definitely be my in my Top 10.
