Do you do this very often?

Singing out loud while listening to music with your headphones on.

Do you experience it?

Someone is singing out loud while listening to music with his headphones on. Whereas the singer gets the benefit of the music, those unfortunate to be standing nearby are subjected to an unaccompanied (and invariably crappy) rendition of the song.

Sometimes my co-works do receive no notification prior to my self-appreiation song, which really make them pissed off.

But singing the song could relax my attention,especially when i am always at sixs and sevens, loose ends.
