If you are like 1UP, one of the things you were most excited about was when Harmonix announced Nevermind from Nirvana as a full downloadable ablum on Rock Band. There's just one problem, Harmonix never said such a thing.
In a day and age where news is reported in split second blog posts, a lot of times things get taken out of context. Rock Band 2 was on display at a certain social gathering tonight, and Harmonix Community Manager Sean Baptiste was there. According to Baptiste, they never specifically announced Nevermind would be available, it was simply given as an example of classic albums that could appear on the service.
