"pop'n music Animelo 2
" was the most expensive Pop'n Music, due to its song list consisting completely of anime as well as television show licensed songs. This version is also the only one with the infamous "double
" and "triple" modes. These options were originally provided with the intention of allowing multiple people to play along by adding one or two more notes for every note in the chart, sometimes resulting in a chord of all nine buttons.
