Well, bottom left number is BPM. Bottom right is the song key. The top number must be the number of the song in the sequencing software or something. That is, the song number matches from night to night and doesn't change. For example, in today's picture, Dirty Epic is 30 and Kittens is 31, the same numbers they had on the
Vegas setlist.
And they had
60 songs sequenced after Malta and Spain earlier this year. With "Diamond Jigsaw" and "Between Stars" being numbers 66 and 67, respectively, that's about right.
Anyone wanna go through the setlists and match songs to song numbers?
