Dirty Disc after DLC

[mxmarks]

Just wondering if anyone else has had this - sometimes after playing the last song of a set, if that song is DLC I'll end up with a dirty disc error. A lot of time wiping the disc will make it go away - but the disc never LOOKS dirty, and Im wondering if wiping it wasnt the fix, as much as turning off the XBox to take the disc out, and then re-starting the game is.

Anyone else have this problem?

I get this error every now and then as well............
The only thing to do is reboot the game.
