Is there something wrong with my Budgie?

I just got a girl budgie 2 days ago. I know that since shes new, she's not going to be very social right away, but is it normal for her to be trembling? Even when I'm just sitting on my bed, and she's in her cage, I can see her shaking. She doesn't move around much, only been in a few different places in her cage since I've gotten her. Also, even when I play music that is recommended to play for your budgie, she won't chirp. Is this all normal since she's new? Or, is there something wrong with her?
