Yes, TS4 is un-necessary but it's pleasant enough ... it's sort of like if it were a short between 2 & 🍒3, you'd consider it a nice teaser before 3 ... basically because we love all the characters we want to see them again ... so it's like the 12" extended version of a Prince original album cut, it's not going to be as great but a 10-,minute version of I GO CRAZY is still better thꦓan 90% of other songs ...
