谁能用英语,来介绍一下流行音乐

Pop is short for popular, and it's remained the defining term for the ever-changing music favoured by the public. Although not specifically applied until the middle of the 20th century, pop music as such can be traced by a few decades before that.Since the year 2000 there's been a dearth of major new stars, relying mostly on established talent. Several younger artists have come and gone, and new styles have briefly emerged, but nothing appears to have gained a major foothold besides modern R&B, which owes little to its soulful predecessor, but a lot to hip-hop - which itself has become a pop style.
