So I've not seen "& Juliet" yet, but as an ardent Britney stan and student of Max Martin's songwriting and production methods, this feels like a must-see for me.
Much as I love the songs included, I would be in favor of a shakeup of the song list with some of Max's more overlooked classics and newer hits.
Personally, I'd want all of the Dr. Luke-credited songs to go, for obvious reasons, but I concede that only 6 of the 29 appear in the musical.
Some of my personal recommendations would be Sam Smith's "How Do You Sleep?", Robyn's "Do You Know (What It Takes)", the oft-ignored predecessor to "Show Me Love", and this is pure pipe dream material, but I'd love to see Solid HarmoniE and Jessica Folcker songs included to help reintroduce them to new audiences.
Finally, and most importantly, HOW IS THERE NO TAYLOR SWIFT SONG??? "Wildest Dreams", "Blank Space" and "...Ready For It?" would be fantastic, but my personal favorite would be "I Did Something Bad" at a pivotal moment during the musical.
Now, I'm no theatre producer, nor do I plan to be, but I would like to see & Juliet explore Max's discography beyond just his big hits.
