They literally pressed play on a tracklist set to random. You could tell because the songs were *exactly* the same as the album version, and when they stepped away from the equipment, the song played as it does on the album. Note for note, beat for beat. Once or twice, I could see that they were messing with the track, but it was 90% finished track. They only added a tiny filigree. The singing was live, I think, though they could have been singing over ther same backing tracks as the albums. The visuals were cute, but not worth seeing. This was a waste of time and money. Or I'm wrong, and these dudes are as efficient as machines.
