I was pretty much the only person in the group that would dig into filters. I think most people didn't even know they existed.
It was hilarious though when you realized you had enough DLC in a genre to basically activate Rock Band: <Genre> mode
I used the filters every time I played. I have a big library though.
I also miss the ability to jump quickly between the first letter of band titles. I haven't bothered with trying the searching, but perhaps that says something about having the navigation built-in. I'm probably avers to having to search as people were to use the filters.
Also, I posted this in the GH review thread, and was curious about the take here for those invested in the RB platform:
The one thing that bothers me/makes me nervous about the possible success of this game is the GHTV service's use of non-separated tracks and its effect on the music genre. It's more like playing over the music. Essentially you could get the same thing from customs.
I don't want to see the significance of getting master tracks diminished, and it affecting Rock Band negatively as a result, either by labels stopping giving access to them or people passing on RB tracks, thus hurting that series, because they can get these much cheaper(?). The separated master tracks are, to me, what made these games the most interesting and cool. The difference between playing a game with individual instrument tracks from the actual bands that you control versus playing along to song is huge.
