Every time I brought up multiple bands in one game the answer I got was too much for licensing. I've tried a few times to talk Jack into securing the "Now that's what I call music" rights... if you could secure that you would have over 65 cds to choose music from. We're talking every band and every type of music hit you could think of from every decade. How you would even be able to choose which songs to use would be the hardest lol. You would be able to make any toy or band feature you wanted in the play field from that song.. there's so many options it's crazy... best part it's only one license for all the music.. feel free to send this idea to any major pinball company
