Hey guys, I'm an admin for Kim Petras Wiki, and I just made some lists there that might be interesting for you guys:
List of Unreleased Songs (Includes titles, pre-Dr. Luke songs, all leaked songs I could find)
List of Covers (Includes all the covers she did on her old Youtube channel)
List of Youtube Videos (Includes all vlogs and videos I could find from her old Youtube channel)
Now I'm working on finding new and old interviews (that pretty much just talk about her transition), so you should check the wiki out if you like Kim
