But other than that—and specific genres that have derived from names of places, like Europop—we don’t need to capitalize things like Rap, Rock, Hip-Hop, etc.
According to most style guides, nouns, pronouns, verbs, adjectives, and adverbs are the only words capitalized in titles of books, articles, and songs.
Do capitalize most chronological periods of music history (the Renaissance, the Baroque, the Classical era, the Romantic piano). But don’t capitalize “medieval” (the medieval motet). Don’t capitalize genres (use opera, symphony, jazz– not Opera, Symphony, Jazz).
The vast majority of music genres are not proper nouns, and thus should not be capitalized.
Just to answer your question: the blues, blues, classical, jazz, hip-hop, trance, psychedelic, trip-hop, atonal, impressionism, neo-classical—none of these are capitalized.

: AP Style tip: Wondering if it’s hop hop or hip-hop, with a hyphen? AP style prefers hip-hop. Well, it’s definitely not “hop hop”.
Genre Exception For R&B
Since R&B is short for rhythm and blues, you want to capitalize bother letters. Writing these letters both in lower case will obviously be recognizable, and I’m sure you could get away with it, but most professional publications capitalize the letters in this genre.
Music genres like blues, rock ‘n’ roll and classical are lowercase.
Musical Eras Capitalize historical musical eras- Baroque, Classical, Romantic. However, when distinguishing classical music from popular music, that is not capitalized. (Words like “classical” and “romantic” are not capitalized when used as adjectives.)
It is a common misconception that short verbs with only two or three letters (is, am, are, be) should not be capitalized. However, this is not the case. All verbs should be capitalized when used in song titles. This includes even the shortest helping verbs.
Generally and grammatically speaking, put titles of shorter works in quotation marks but italicize titles of longer works. For example, put a “song title” in quotation marks but italicize the title of the album it appears on.
A popular urban culture, associated with rap music, breakdancing, etc.
Hip-hop [sometimes spelled hip hop, without the hyphen] is often identified as just a music form, but it goes well beyond music.
