Music Informatics for Radio Across the GlobE (MIRAGE) MetaCorpus (v0.2)

Overview

Welcome to the Music Informatics for Radio Across the GlobE (MIRAGE) MetaCorpus. The current (v0.2) development release consists of metadata (e.g., artist name, track title) and musicological features (e.g., instrument list, voice type, tempo) for 1 million events streaming on 10,000 internet radio stations across the globe, with 100 events from each station. 

Users who wish to access, interact with, and/or export metadata from the MIRAGE-MetaCorpus may also visit the MIRAGE online dashboard at the following url:

Data Sets

The metadata reflect information about each event's location (e.g., city, country), station (name, format, url), event (id, local time at station, etc.), artist (name, voice type, etc.), and track (e.g., title, year of release, etc.). For that reason, the MIRAGE-MetaCorpus includes the following datasets:

MIRAGE.csv -- the complete metacorpus (1 million)

events.csv -- all event-level metadata (1 million)

tracks.csv -- all track-level metadata (414,886)

artists.csv -- all artist-level metadata (259,783)

stations.csv -- all station-level metadata (10,000)

locations.csv -- all location-level metadata (4,324)

A subset of the MIRAGE-MetaCorpus is also available for events with metadata from online music libraries that reliably matched the event's description in the radio station's stream encoder:

MIRAGE_reliable.csv (473,850)

events_reliable.csv (473,850)

tracks_reliable.csv (204,969)

artists_reliable.csv (80,005)

stations_reliable.csv (9,284)

locations_reliable.csv (4,142)
