People keep bringing over and over again that Ayu turned out into shit as a performer on those past years because the keeps performing the same songs over and over again, so, I'm super busy and my brain needed a reason to procrastinate, and I took a look at the setlist of every tour she had during her 2nd decade. I didn't look up into CDLs, A-Nations, TA Tours or random festivals and lives, because I was too lazy to do that and nowadays the tours are where most people will se her performing anyway.
She performed a total of
130 unique songs without counting interludes, what means
an average of 16 unique songs per tour, almost a whole concert the size she would perform on her first 10 years.
Per tour, without counting interludes (and ignoring most old tracks from PoM were completely rearranged). I'm also not counting "non classic" tracks that are overplayed but aren't released on the past 10 years (like BoY, mnW, STEP you, etc)
What conclusion I take from that? That aside from evolution, SURREAL and Boys & Girls she is always trying to favor "recent" staples over older ones. That ABL aside, +- 3/4 of her tracklists consists of either very recent songs or underperformed older tracks.
BTW, it's very clear she is performing less and less tracks from the same year, but she is also releasing less and less tracks every year, so...
