Back-to-Back Falsettos: A Query to Vocologists

Taken from Freeform Voice Progress Talk: The Joy of Falsetto, The Mutual Re$pect Gang - It Feels Good (to Be Alive), and a recording I made 30 minutes ago (08-07-24, 02:47). First clip was recorded 17-03-24, and second clip is from somewhere in the time of '07 (I'm somewhat certain).

Yes, I am the same person, but you may notice something different about the quality of my falsetto through these recordings!
