 ### Dataset Summary
 
-This dataset consists of roughly 480k english lyrics with some more meta data. The meta data was taken from the million playlist challenge @ AICrowd. The lyrics were crawled using the song and artist name with the lyricsgenius python package. There is no guarantee that the lyrics are the correct one though the data was cleaned and verified. The lyrics crawled came with the song name in its payload, if the song names in the payload and from our side don't match (using the package fuzzywuzzy string matching with a score of under 60) then it wasn't included in this set of lyrics. Still some lyrics might be wrong due to the nature of the data.
