I think part of this is culture. I grew up in North America, and when I visited the Philippines later in life, and went to watch shows in concert or in clubs, I was shocked at first because the audience would, without fail, applaud or cheer when the singer would sing the first line of the song. On account of my western upbringing (especially with regard to classical music), I was somewhat scandalized, and almost felt upset at my fellow audience members. I soon learned that, in doing so, they did not intend any disrespect, either to the performer or the rest of the audience, but rather were showing their support, appreciation and enjoyment of the musician's offering. A sort of "two-way" concert experience. I suppose that, if most of the audience wants silence, it's respectful to keep silent during performances. At the same time, if most of the audience isn't concerned about that, I suppose it isn't that big a deal?
