Why worry? I mean I was disappointed too. But then I reminded myself how the very best films, books, etc. never achieve the sales of more populist fare and feeling suitably elitist and smug I ceased to worry about LBP sales.
Also I've been too busy getting to grips with level building.
As for music we have a real drum kit, guitar, etc. in my house, none of this pretending with controllers malarkey for me.
Try to be reasonable... its easier than you think...
