This is what happens. It's pretty common knowledge that the dots mean the song has backing tracks, which means anything from backing vocals, strings, to an actual drum or guitar track underneath the mix to fill out the sound. Now that Jon went ahead and mimed 1 performance, all of a sudden people imply that they're 100% sure the dots mean those songs are playback. 1 stupid decision, and now the entire integrity they've always had is suddenly in doubt....
