And just because a million people play it from time to time does not mean that all, a majority, or even half of those people buy some or even any dlc.
Like I said, hmx stated back in the hey day that players averaged 2 dlc songs. Not a week. Not a month. Not a year. That's 2 songs period.
People playing a 2 year old game from time to time does not make hmx money. People need to buy dlc. Less and less people are doing that.
Blitz is definitely an attempt to fix that.
