The sound was different when she started singing the cutesy songs... it was like "changing track now"
at08:I still think that Marionette wasn't playback... they have fixed her voice from the tv reports to the tv news (she wasn't breathing and projecting her voice in the right way in the reports, but that was fine on the DVD)... The mic-sounds can be taken off with singing classes and sound programing (the better the singer, the less he/she will make that sounds... and you can program the sound to eliminate most of it, even live).
At07 I think you may be sure about the ground part... I saw some people saying that M wasn't live, but she was having a hard time singing this (even if she was smiling, you can see that she was getting tired and her neck veins were about to explode
). But at07 sound is VERY edited... I don't think that we can say what was live and what wasn't based on the DVD... there's a fan recording of evolution, gonna search for it
At06: the only thing I know is that one day the ball wasn't moving and she had to sing alterna, is this love and (miss)understood there...
At05: She was moving slower than she was at at08 in MNW, I think it's live (she herself confirmed the playback at happy ending)
AT0304: I'm pretty sure it wasn't live... she used the same pre-recorded version on mtv superdry live
