In a previous post I showed how to use data science tools to find hidden features in unstructured text and analyzed how the complexity of the lyrics of Beatles songs changed over time. In this post I do a little follow-up and compare complete works of The Beatles with that of two others using the same methodology and metrics. Comparing Beatles with other musicians may help put the original numbers into the perspective.

The Beatles became a hit through its sometimes simple but always powerful music but it has never been famous for its poetry. The group’s lyrics, however, did change during the band’s short existence and we can use text analysis to track these changes. This post is about measuring the change in the complexity of the group’s lyrics, from the Please, Please Me to the Abbey Road albums, showing how we can use basic data secience tools to find really fancy patterns in unstructured text data.
