I surveyed many of J-Music and anime music listeners amongst my friends, and somehow found something out -- there aren't many of them to know about Maaya Sakamoto and/or her songs.
I think it's kinda odd, since, IMHO, Sakamoto-san sang so many high-quality anime songs. To name some, "Tune the Rainbow" from RahXephon movie, "Cloud 9" and "Gravity" from Wolf's Rain, and also "Loop" from Tsubasa: Reservoir Chronicle.
What about you guys here? Is there any Sakamoto-san's fan here? Oh, and please mention the song you like from her, too. :) Just want to know.
