Tables

train.csv

  • genre_ids: genre category. Some songs have multiple genres and they are separated by |
  • artist_name
  • composer
  • lyricist
  • language

members.csv

user information.

  • msno
  • city
  • bd: age. Note: this column has outlier values, please use your judgement.
  • gender
  • registered_via: registration method

  • expiration_date: format %Y%m%d

song_extra_info.csv

  • song_id
  • song name - the name of the song.
  • isrc - International Standard Recording Code, theoretically can be used as an identity of a song. However, what worth to note is, ISRCs generated from providers have not been officially verified; therefore the information in ISRC, such as country code and reference year, can be misleading/incorrect. Multiple songs could share one ISRC since a single recording could be re-published several times.
