Just to clarify a little - its not unusual for a seiyuu to have lots of work in anime before she has a solo CD. 3 years ago was her first Solo CD. Broken Bird was her second, and it came out right as she left the stage. Girl Phase was already in its third season by this time.
Useless info in many ways, but maybe that will keep you from trying to tie your brains in knots figuring things out. She was already quite famous at this point.
