Category talk:Songs sung by Olivia Olson

Merging and Re-Merging
In my opinion, we should merge this page with "songs sung by Vanessa Doofenshmirtz", technically, her voice doesn't change for making one or other thing, it would be different if she change her voice as Dan makes for voicing or Doof or songs by himself, but I think that this page should be merge, the same with songs by Jeremy that should include the songs performed by Musso out of screen
