I'm not really sure if the lyricst Uran is the same as the performer UR@N. Uran does lyrics for a lot of animes and almost nothing what she worked on is listed on UR@N's website under her works. UR@N, on the other hand, rarely does lyrics and if she does than she also performs the song. Also, she seems to do mainly game related works.
Moreover, the japanese wiki has got a entry for UR@N but for "うらん" there are 4 different possibilites, among those "Uran (lyricist)" (w/o entry).
I wonder if those two shouldn't be seperated?
EDIT: I made a new entry for the lyricist Uran and seperated the ones UR@N definitely didn't do.
What might be interesting is the fact that Uran really often works on animes that Kaoru Okubo composed music for.
