Additionally, they are investigating implementing metadata from open music encyclopedia MusicBrainz
(http://www.music brainz.org) so that track listings, genre, and recording participants (i.e.
FlaBase combines information gathered from general KBs (e.g., Wikipedia, DBpedia), online music encyclopedias (e.g., MusicBrainz
[https://musicbrainz.org/, accessed 16 September 2016]), and specialised flamenco Web sites (e.g., http://www.andalucia.org [accessed 16 September 2016]).
Six popular music datasets; RWC database, GTZAN genre collection, Uspop2002, MagnaTagATune, Musicbrainz
and MSD; were benchmarked based on relevance, quantity and quality.
With data pulled from a range of sources, including Wikipedia, Open Library, MusicBrainz
, EDGAR, and the Integrated Taxonomic Information System, Freebase consists of data links from many reputable sources.
Semusic supports searching those objects with information integrated from open datasets of music such as MusicBrainz
, Wikipedia, and Tinysong.
The work is divided into sections by data type covering websites, people by email, people by name, people by account search terms, locations, companies, IP addresses and book, film, music and product names and individual entries deal with entities such as Flickr, Amazon, LinkedIn, Yahoo!, Bing, Google Shopping and Musicbrainz
. Each entry includes useful example code and advice for accessing the resources.
This emerging web of data includes data sets as extensive and diverse as DBpedia, Geonames, US Census, EuroStat, MusicBrainz
, BBC Programmes, Flickr, DBLP, PubMed, UniProt, FOAF, SIOC, OpenCyc, UMBEL, Virtual Observatories, and Yago.

Metadata in the Spotify system comes from dedicated external sources: MusicBrainz
(track and album tags) and AllMusic (biographical information and images).
Amidst the fury over the loss of a database users believed would always be free, open source alternatives such as freedb.org and MusicBrainz
began as permanently-free replacements.
