Although I enjoy listening to the Barcelona concert as a whole, WAM from that concert is not one of the best, so I wonder why it was selected when around 80 other much better versions were available? 
It was "selected" simply because it is the first song from the first concert. The songs are both in setlist order and chronological order (save for BIA at the end), which is mathematically impossible if you select a "best of" using your judgement. There was no human decision involved. shame !
So not a "best of" at all, in fact. 
To be fair, though, it would have been an almost impossible task to select the best version of each song from all 87 concerts - it is just a compilation and it is a freebie, so I'm not complaining. 
Well, in 2015 they made 2 best of (European and North America) which made much more sense. Every song was featured, and the versions that were selected were of course debatable, but at least were chosen by a human, and definitely they were not the worst versions. This is a huge step back. Although I don't care, I made my own compilation using my jugement and preferences, but still - even such as simple task as that, MK. com is unable to do properly...
