@sugarbasil: I know how you feel
I was also a big fan of the InuYasha series and then all of a sudden 12 year olds became crazed and annoying fans, saying that Inuyasha was the best anime ever and that they resemble with their favorite characters (Kagome, Inuyasha etc) until I had enough and didn't want to hear of IY again -_-
Oh well, those were the past, no crazed IY fans in these days ^_^;
And to be ontopic: Well, who knows? Maybe she'll do a song for IY... but, times had changed since her I am... era, her recent music (in my opinion) dosen't really fit with an anime like IY
