Don't see that myself, she's not exactly a big star on the show, or off of it.
Clearly the writers like her singing, for contrast. Could do without it myself.
Don't mind her as an actress though, and I hope she takes over some of Andrea's Comic plots.
She has a good voice. Would be better them recording a song and having it over last scene/credits etc.
I hope she gets more to say this season though.,
