Full Moon - I can see something like austin's idea where we see Namie leading a guy into a sort of forest-type place where they start making out and stuff but then the moon comes out and Namie's eyes change and we get like flashes of the guy getting his clothes torn and stuff.
It's all about you - I can see multiple TV screens and stuff and Namie dancing like in alleyways and stuff
Step With It - just lots of dancing 0_0
Should I Love Him? - Namie is in some big fancy restaurant with a guy eating a meal and laughing and giving him little looks and smiles where you can tell she's happy. Then it cut to Namie in a house beside a huge window, the sun coming up outside and Namie singing. Then at the end the guy at the restaurant walks over to her and holds her and the video ends with Namie smiling happily at the screen
Top Secret - I'm thinking at Mr. & Mrs. Smith parody sort of thing with Namie playing the role of Angelina Jolie and some dancer as Brad Pitt. It switches between a tango bar and maybe them doing spy stuff
Violet Sauce - AyuHamasaki01's idea of Namie dancing in Sin City
Pink Key - something with cherry blossoms
