Medley Tour goes through the songs one at a time like Iron Throne does with houses on Game of Thrones. You complete all the song shots and move on to the next song. I haven't seen Final Tour yet, but now that the Elevator roadblock is gone, I will try it again. I got all the other modes and MB completed before, but got blocked by that. Elevator MB is not easy to complete.

9 songs total (that I know of), 2 of which are in MB (Toys in the Attic & Love in an Elevator). The other 7 you can select. Song runs until timer runs out. Hitting lit shots extends timer as does shooting scoop when Crank it Up is lit. Crank it Up is like away team missions on Star Trek. Modes are basically the same as KISS. Shoot lit shot, other shots will light. Shoot in succession and double the value. It uses the whole playfield, unless it is an orbit specific mode, then it will be fixed with both orbit shots lit. Once you get far enough in the mode, a super value will light like Super Ramps for Walk This Way.

Spelling AEROSMITH by hitting on the letter standups starts double scoring on the Pro.

I thought it was double scoring for 20 seconds during normal play, but I could be wrong.
