Analyze Data for Albums, Bands and Songs
The Wolfram Language contains deeply connected data about popular music, with "MusicAct", "MusicAlbum" and "MusicWork" entities. For example, given a song, you can construct an implicit entity class to find notable musicians and music acts who have recorded versions of it.
You can also find all works written (or cowritten) by a musician and then find all the musicians and groups who have recorded any of those songs.
Retrieve the country of origin for each of those acts, and generate a geo histogram of countries weighted by number of music acts.
