People confuse pop music with popular music but it is not like that. They are distinct. A generalized dictionary of music defines popular music as the music which attracts most of the tastes and interests of the urban people. Pop, on the other hand is evolved from rock n roll genre of music. During the 19^th century, it is regarded the music with high number of listeners and topping number one in charts as the rock n roll genre. Since then it evolved as pop music comprising some of the qualities of top music. Pop music has an identifiable characteristic of comprising pop song. The lyric is not usually written during the production and may sometimes have meaningless words.  The same lyric is repeated by chorus and this brings enthusiasm when hearing again and again. Pop music now began to disintegrate by losing its own peculiar nature. It starts to borrow elements from other music genres such as country, hip hop, rock, etc. But there is one kind of music which is considered as true pop music, which is, pure pop. It is shorter in length and mostly performed on an electric guitar, drums and bass. It contains one or two catchy phrase that is repeated by the chorus.
