This page explores my music listening history, as recorded by Deezer (a streaming platform).
The history goes back to 2016, but there are substantial chronological gaps where I didn't have an active subscription. I have tried to hide these gaps as much as possible where appropriate, instead of showing large stretches of sparse data.
The overall source data quality was moderate and I've had to clean it up in places, for example unifying naming or formatting conventions which led to the same artist/track being listed multiple times under different names. There might still be odd issues relating to this.
Genres: The artist genre classifications are pulled from MusicBrainz, and I haven't reviewed them much. I intend to do more curation, but genre is a bit subjective anyway and I didn't want to get bogged down in it. The genre classification is at an artist level; usually this is adequate but some artists switch genres. The most visible issue arising from this is that Metallica are (correctly) classified as both Thrash Metal and Hard Rock, but Master Of Puppets is not a hard rock album and Nothing Else Matters is not a thrash metal song. Classifying genres at the track level is the only way to resolve this, but adds complexity. The average artist in my history doesn't radically switch genre (Metallica is probably the worst offender), so tying genres to artists provides an adequate result.
Artwork: Artist and album artwork have been fetched from external sources. I have not reviewed them all. Many are missing and some may be wrong.
Identity: Entities (i.e. artists, albums and tracks) are considered unique by name. If two artists have the same name, then they're considered the same. I'm not aware of any instances where this comes up in the data. If an artist re-releases a track without renaming it, then it's considered the same. This includes remasters, re-recordings and live performances - the former of which is desirable, the latter two less so.
Multiple artists: A track with multiple artists results in those multiple artists being treated as one (e.g. "Alice Cooper" is an artist, "Rick Wakeman" is an artist and "Alice Cooper, Rick Wakeman" is also an artist because they performed together on one track). I am not really happy with this but I haven't yet decided how better to handle it.
