Fair enough, I guess so what do you do? Not have games with songs? Have acoustic only versions? Would think TBL has a couple things going for it to help here (without inventing some scheme to hide the licensed songs like the papa commenter suggested)
List of songs:
1) the music is all across the board in style (so not overly monotonous).. Realizing the code is alpha here so may be using the same song too much since the modes that would be associated with a lot of songs are missing
2) from expo talk (by Phil) you progress through scenes of the movie.. I.e., the music may be progressive in that you're going to hear new stuff as you get to it.. Vs acdc.. All songs are available cause the modes are all available.
3) some of even the licensed songs are non vocal plus there's room for filler music (bop2.0 has non licensed tracks that seem cool), plus one of the DP guys on their website is an audio guy.
4) its beaglebone and proc based.. If sharp guys can build a pinball browser for stern, me thinks you can probably ruin your TBL with poor music choices on your own
I guess I had a strong reaction to the papa comments in the 'let's hide the songs with crappy versions you have to earn" - some of us are not pinball gods I want my game to boot up, play tumbling tumbleweeds dammit!
