A thought…
What if small recorders/sations actually used the last Fm or your music profile to play a sample of your favorite tune. In the same manner as the karaoke tune chooser. And then you could physically check if you have the same taste in music. Everytime a new person toches he song will change.
This could be fun to do, and maybe when you touch the wall only people with the same taste are being displayed. And maybe this could trigger interesting footage as well.
