Hi there !
For you, wich music is the best for tickling ?
My choices:
Carmen Miranda - Tico Tico no Fuba
Las Ketchup - Asereje
Sigue Sigue Sputnik - Love Missile F1-11
Leroy Anderson - The Typewriter
EDM music is usually my go to. It usually has a mix between starting with lower energy and a steadily increasing beat and intensity. It slowly elevates with multiple big bass drops and high volume sections. It's messes with your ticklee's mind as they hear the music slowly increasing because they know the tickling is about to be unbearable when that chorus hits and the energy peaks and the fingers tickle more and more intensely to match the music.
Example songs:
Sandstorm by Darude
Weaponize by Pegboard Nerds
Beastmode by Teminite
Alone by Marshmello
