I started off back in 2004/5, and I didn't really become a fan until 2006 (it was around May), and later on I realized I love Ayu more than anyone else. I also had a really hard time back then, and her music helped me a lot through it. As truehappiness said there are a couple of songs I know well but I rarely listen to them nowdays. I don't listen to her 24/7 as there are many other artists I love, but every few days I kinda have a little ayu session with just her songs shuffling in foobar, and after a couple of songs I am like ok Just one more and I am off to bed XD, though I usually stay up for hours. I never felt like the Ayu magic was gone, sure I am not always in the mood to feel sad/happy about it~ like if I am doing other things like studying and listening to ayu, I won't concentrate on the music that much ^^ so naturally I won't feel a thing.
