Trauma going humming?

[Let-Go]

Hmm well i was wondering, Trauma is a WAY old song that have been there all the time, now ayu has "humming 7/4"...notice both have now a "choreography" or a way to "interact" with the audience just like evolution[but considering trauma is relative "old"...] & trauma...

well i was just wondering if she's changing trauma for Humming in her upcoming tours and such.
I reallly like "trauma", not long ago i found it "plain"...humming is so "bleh" but after watching the performance @ The count down...@-@ i dunno...

You think she should/would change trauma for humming?
