I love percussion, hand clapping, tapping or stamping out the beat on many, many songs and types of songs. However, unless the percussion is the main event, it is not fun when the stomping or clapping is so loud as to obscure or overpower the voice or other instruments, and certainly, some one else tapping and vibrating my seat is always a distraction, even if no music is involved.

I no longer sing, but when I did, I was definitely a clapper or stomper. When really immersed in the song, it can be easy to not notice the physical environment/accoustics of a place may result in the body percussion drowning out or distracting from the song.
