As per wikipedia:-
Folk music
Folk music includes both traditional music and the genre that evolved from it during the 20th century folk revival. The term originated in the 19th century but is often applied to music that is older than that. Some types of folk music are also called world music.
Devotional music
A devotional song is a hymn which accompanies religious observances and rituals. Traditionally devotional music has been a part of Christian music, Hindu music, Sufi music, Buddhist music, Islamic music and Jewish music
Each major religion has its own tradition with devotional hymns. In the West, the devotional has been a part of the liturgy in Roman Catholicism, the Greek Orthodox Church, the Russian Orthodox Church, and others, since their earliest days. A devotional is a part of the prayer service proper and is not, in these contexts, ornamentation. During the Protestant Reformation, church music in general was hotly debated. Some Puritans objected to all ornament and sought to abolish choirs, hymns, and, inasmuch as liturgy itself was rejected, devotionals.
Popular music
The term popular music belongs to any of a number of musical genres "having wide appeal"and typically distributed to large audiences through the music industry. It stands in contrast to both art music and traditional music, which are typically disseminated academically or orally to smaller, local audiences. The original application of the term is to music of the 1880s Tin Pan Alley period in the United States. Although popular music sometimes is known as "pop music", the two terms are not interchangeable[citation needed]. Popular music is a generic term for music of all ages that appeals to popular tastes, whereas pop music usually refers to a specific musical genre.
Classical music
Classical music is art music produced or rooted in the traditions of Western music (both liturgical and secular). It encompasses a broad span of time from roughly the 11th century to the present day. The central norms of this tradition became codified between 1550 and 1900, which is known as the common practice period. The major time divisions of classical music are as follows: the early music period, which includes the Medieval (500–1400) and the Renaissance (1400–1600) eras; the Common practice period, which includes the Baroque (1600–1750), Classical (1750–1830), and Romantic eras (1804–1910); and the 20th century (1901–2000) which includes the modern (1890–1930) that overlaps from the late 19th-century, the high modern (mid 20th-century), and contemporary or postmodern (1975–2000) eras.
