Difference between pop and reggae music
Reggae music is very different from other musical styles in that the emphasis is placed on the off-beat, usually by a rhythm guitar, piano or synthesizer. When people dance to disco or pop music, they move in time with the bass or bass drum beat, but dancing to reggae music involves moving in time with the off-beat.
Similarities :
Although popular music sometimes is known as "pop music", the two terms are not interchangeable. Popular music is a generic term for a wide variety of genres of music that appeal to the tastes of a large segment of the population, whereas pop music usually refers to a specific musical genre within popular music.
