Background:
Due to popular demand, this is the list of all the songs used in Warrior Cats: Untold Legends. I spent about 2 hours hunting down the original source of every one I used with the exception of the APM songs provided by Roblox. Most of them are copyrighted songs, but hopefully the few that experienced these songs in the game will enjoy listening to them 
I'll be updating the list when/if more songs are rediscovered.
