I know there are some people working on some Disney songs here, but I remember reading somewhere that the problem with Disney songs is that they are not exactly fit to be in rock band Disney songs don't have rocking guitar solos, or amazing drum works, I think most of them don't even have guitars.
So I was thinking, hey what about covers for Disney songs, more specifically ROCK covers, and to be even more specific Jonathan Young!
He is a great Youtuber, who has a lot of great covers for these songs, and who knows if someone tries to reach him he might send the files necessary to make life easier.
Here is some of his work, and songs that I wish I could play in Rock Band:
Go the Distance (the guitar is from around the 1 min mark)
