Is the final setlist confirmed? 22 songs only?

Regarding the black dots, are you sure they represent backing tracks? I mean, it is really not very useful information for the band when they are on stage. Even if it did have backing tracks on these songs, what would that mean to anyone?

What I think is that for example, if this is PhilX' setlist, black dots could represent the songs where he plays solos.
So, Shanks maybe has setlist with dots in other places, or whatever..
