年龄稍长的人都抱怨说：现在的流行音乐声音大，而且所有歌曲听起来都一样。事实证实他们说的没错。
It is a familiar complaint from those of a certain age: today’s pop music is louder and all the songs sound the same. It turns out they are right.
研究显示，现代唱片的确比五、六十年代发行的那些声音要大，在和弦与旋律上缺乏变化，听起来单调。
Research shows that modern recordings are louder than those of the 1950s and 60s. They are also blander, with less variety in terms of chords and melodies.
