If the wii 2 is going to include any kind of multimedia functions such as a music player, I have a good idea of how to use it and make it unique. Basically have a music player where I create the miis of my favorite band, assign certain songs to them and then play the music and have some kind of rock concert going on inside my wii 2.
For example, I like the band Godsmack, so I would create the miis of the band such as Sully Erna, the lead singer, and then assign a song like "I Stand Alone" to the band and then play the song. The same would go for any other bands such as Korn or Disturbed.
There would also be sound amplifiers and what ever applications needed to alter the sound of the songs in a similar fashion to what the DSi music player does with soundtracks
