From Nowhere, anime blog:
Composer and singer Okazaki Ritsuko, best known for her work on Fruits Basket, died last Wednesday [20040505] from a blood infection. She was 44 years old.

Okazaki contributed music for Love Hina, Princess Tutu, Stratos 4, Kareshi Kanojo no Jijo (His & Her Circumstances), and UFO Princess Valkyrie, as well as writing music and penning lyrics for artists such as Hayashibara Megumi and Horie Yui.

I'm not particularly fond of her, but this is one less talented composer and singer on this world.
