No the music alone would drive me up the wall. Photoshop is already annoying why add to it.
Seems to me like animation made out of a real software already existing.
1st brush feature is already in Illustrator. Its just 2 step process. Making a brush first and then applying to stroke.
2nd feature of geometry will really be nice but thats a totally different era of cad application which photoshop is not into. Moreover basic requirement of such drawings are vector export and illustrator should be better target for such features. Photoshop cc2018, I think already has 1 auto shape detecting brush which kind of fills the gap too.
