I'm a big fan of Ayu, but I wouldn't call myself obsessed or whatever. I like her music (well, her old tracks more) and I still follow her news. I can't say that I'm the big Ayu fan that I used to be though. For me, Ayu was a lot more interesting back then. She used to always release fantastic singles and albums, she had a really trendy fashion style that wasn't all about being glamorous (gosh, I loved her MTRLG days!!!), her works had more depth then it does now IMO.
But I'll always enjoy most of her songs.
