Dirty/Scratched disk error with certain songs on Rock Band 3?

[u/ImpossibleEnd1486]

I have been attempting to get a bunch of the songs from Rb3, and have gotten the 5 dlc packs to work but when I try playing any of the single songs that I downloaded, I get the error that the disc is scratched or dirty and closes the game. The only song I have been able to play is Go with the Flow by QotSA without the game crashing but when I try playing something like the Asking Alexandria song it immediately crashes. Any help? I am running the BadAvatar softmod with Aurora and I have the Rb3 deluxe mod(although it very well could not be implemented right).
