Song Selection by Vote

[Bwinter]

Last year, i believe there were several people that were implementing a system that would allow the crowd to vote to have a bit of control on choosing the next song.


I don't think I've seen anyone provide a "post-season analysis" of how well that worked, was it effective, or other thoughts on whether or not it enhanced their show.


I'm not so much interested in the *how* it was accomplished.  I'm more curious about how well it went, how frequent was it used, etc.
