As a result, lyrics of rap songs have often been treated as "confessions" to a number of violent crimes in the United States. It is also considered to be the duty of rappers and other hip hop artists (DJs, dancers) to "represent" their city and neighborhood. This demands being proud of being from disadvantaged cities neighborhoods that have traditionally been a source of shame, and glorifying them in lyrics and graffiti. This has potentially been one of the ways that hip hop has become regarded as a "local" rather than "foreign" genre of music in so many countries around the world in just a few decades. Nevertheless, sampling and borrowing from a number of genres and places is also a part of the hip hop milieu, and an album like the surprise hit "Kala" by Anglo-Tamil rapper M.I.A. was recorded in locations all across the world and features sounds from a different country on every track.
