And not just those games either – ANY console games that allow players to buy music downloads. The UK’s Official Charts Company says it wants to include these sales in its Official Download Chart alongside sales from more traditional digital retailers.The OCC says it’s in discussions with game publishers and record labels to make this happen by the end of the year. “The information we have to date suggests that the incredibly successful Guitar Hero and Rock Band franchises can generate significant volume of master recording downloads that we would like to capture within our weekly survey,” says OCC chart director Omar Maskatiya.In-game downloads are becoming a standard feature of console music games: besides Rock Band and Guitar Hero’s latest incarnations, there’s Sony’s SingStar for PS3. If the move goes through, it will be interesting to see if it gives rock songs a leg up the charts.
