None of these are relevant to the idea that rappers in this 3 year stretch struggled to blow up.
I'm not sure how far back of a "legacy" you're looking at but the early to mid 00s had plenty of multi-platinum rappers. Nobody was struggling to sell due to the "fall of labels" yet. Those legacy artists simply had their time.
All that is irrelevant and after the fact, by the late 00s his glass ceiling was already set. This is why I said too much retrospection is being used.
You can apply a bunch of after-the-fact fuçkery to Game and personal issues to artists in general, Game still had a successful career due to his initial blow up.
