Although most of the book's recommendations are rock and pop albums from the Western world, "1001 Albums" also features selections from world music, rhythm and blues, blues, folk, hip hop, country, electronic music, and jazz.
The rock and pop albums include such subgenres as punk rock, grindcore, heavy metal, alternative rock, progressive rock, easy listening, thrash metal, grunge and 1950s-style rock and roll.
Classical and modern art music is excluded. 
Pinoy rock, or Filipino rock, is the brand of rock music produced in the Philippines or by Filipinos.
It has become as diverse as the rock music genre itself, and bands adopting this style are now further classified under more specific genres or combinations of genres like alternative rock, post-grunge, ethnic, new wave, pop rock, punk rock, funk, reggae, heavy metal and ska.
Because these genres are generally considered to fall under the broad rock music category, Pinoy rock may be more specifically defined as rock music with Filipino cultural sensibilities.
It is very easy to identify a Pinoy rock song because the lyrics are often in Filipino, Tagalog, or any other language native to the Philippines. 
Alternative metal (also known as alt-metal or hard alternative) is a style of heavy metal.
Alternative metal usually takes elements of heavy metal with influences from genres like alternative rock, and other genres not normally associated with metal.
Alternative metal bands are often characterized by heavy guitar riffs, melodic vocals, unconventional sounds within other heavy metal genres, unconventional song structures and sometimes experimental approaches to heavy music.
The term has been in usage since the 1980s, although it came into prominence in the 1990s.
It has spawned several subgenres, including nu metal, which expands the alternative metal sound, commonly adding influences from hip hop, groove metal and thrash metal. 
Latin Alternative, or Alterlatino, is the brand of latin music produced by combining genres like alternative rock, electronica, metal, New Wave, pop rock, punk rock, reggae, heavy metal or ska with traditional Latin American sounds.
Because these genres are generally considered to fall under the broad Rock en Español or Latin Rock category, media coverage started to use the word 'Latin Alternative', especially in the United States. 
Scratching has been incorporated into a number of other musical genres, including pop, rock, jazz, heavy metal and classical music performances.
For recording use, samplers are often used instead of physically scratching a vinyl record.
Rage Against the Machine (and former Audioslave) guitarist Tom Morello performs scratching-inspired guitar solos.
In the song "Bulls on Parade", and many other songs in which he solos, he creates scratch-like rhythmic sounds by rubbing the strings over the pick-ups while using the pick-up selector switch as a cross-fader.
Since the 1990s, scratching has begun being used in a variety of popular music genres, such as nu metal acts (like Linkin Park, Slipknot and Limp Bizkit) and in some types of pop music (e.g.
Nelly Furtado), and in some types of alternative rock (e.g.
Incubus).. Scratching is also popular in various electronic music styles, most particularly in hard-groove techno.
