K歌 與POP SONG嘅分別

Pop music (often called simply pop) is a genre of popular music distinguished from classical or art music and from folk music.[1] The term indicates specific stylistic traits such as a danceable beat, simple melodies and a repetitive structure. Pop music often includes elements of rock, hip hop, reggae, dance, R&B, funk, and sometimes even folk. The pop music genre often involves mass marketing and consumer-driven efforts by major record companies, which makes it an often scorned genre by other musicians.
Karaoke (カラオケ, Karaoke? 空 kara, "empty" or "void", and オーケストラ ōkesutora, "orchestra") pronounced [karaoke]; listen (help·info) is a form of entertainment in which an amateur singer or singers sing along with recorded music on microphone. The music is typically of a well-known song in which the voice of the original singer is absent or reduced in volume. Lyrics are usually also displayed, sometimes including color changes synchronized with the music, on music video to guide the sing-along.
What is thought of as karaoke today was popularized by the Japanese singer Daisuke Inoue in Kobe, Japan in 1970 [1]. After becoming popular in Japan, karaoke first spread to East and Southeast Asia during the 1980s and subsequently to other parts of the world.
