I mean if a filter says it will hide songs, and then it hides songs, a person should expect that to happen and not go "ZOMG, WHERE'D MY SONGS GO?!? I'M CALLING HARMONIX THIS WILL NOT STAND!".
If the above player is the one they are going to target as their primary consumer and tweak the game to suit, then I think we are all in trouble.
That IS what you are saying the majority of players would do, unless I am misreading you now.
Then you go on to say that this would be "the majority" of the game's players.
I don't think you are correct in either case, if this is your assertion and I don't think you've said anything to make me think otherwise. If that were so you would have kept your fingers still and not taken this role in the conversation at all.
In other news this is a real place and GNF works here.
I mean it's not like you might accidentally not share DLC with another person, can you?
And if someone dictates a scenario where you -could- forget you don't share DLC or other such nonsense, then I suggest that you might just be arguing for the sake of arguing and refer you back to the link I posted just above.
