So am i correct in thinking that Cold by Crossfade is the highest selling single from this pack so far and The Weight is the least? I'm using the Rockbandscores dlc popularity section as an indicator of this, no hard facts. Either way I'm not surprised by either.
Rockbandscores just got fixed yesterday, give it a day or two to start pulling data correctly. I don't think every instrument on every platform has processed yet.
