Love Me, Love Me, Say (and Write!) that You Love Me:Enriching the WASABI Song Corpus with Lyrics Annotations
Table 1: Lyrics segmentation performances across musical genres in terms of Precision (P), Recall (R) and F1 in %. Underlined are the performances on genres with less repetitive text. Genres with highly repetitive structure are in bold.

The lyrics consists of seven segments and shows the typical repetitive structure of a Pop song. The main diagonal is trivial, since each line is maximally similar to itself. Notice further the additional diagonal stripes in segments 2, 4 and 7; this indicates a repeated part, typically the chorus. Based on the simple idea that eyeballing an SSM will reveal (parts of) a song’s structure, we proposed a Convolutional Neural Network architecture that successfully learned to predict segment borders in the lyrics when “looking at” their SSM. One important insight was that more repetitive lyrics as often found in genres such as Country and Punk Rock are much easier to segment than lyrics in Rap or Hip Hop which often do not even contain a chorus.
