LyricWiki Collection<br />

Number One Hits<br />

Figure 1: Boxplots showing the quartiles of lyric<br />

scores for the lyric collection from the 1990-2010<br />

era, and the corresponding set of number one hits<br />

from the era.<br />

hits are indeed more typical than other songs,<br />

or perhaps that a song that reaches number<br />

one influences other lyricists who then create<br />

works in a similar style. Earlier attempts to<br />

compare number one hits with the full collection<br />

of lyrics revealed an increase in cliché<br />

score over time for hit songs. We believe that<br />

this was not so much due to an increase in<br />

cliché in pop over time but that the language<br />

in the lyrics of popular music changes over<br />

time, as happens with all natural language.<br />

6 Conclusion<br />

We have explored the use of tf-idf weighting to<br />

find typical phrases and rhyme pairs in song<br />

lyrics. These attributes have been extracted<br />

with varying degrees of success, dependent on<br />

sample size. The use of a background model<br />

of text worked well in removing ordinary language<br />

from the results, and the technique may<br />

go towards improving rhyme detection software.<br />

An application was developed that estimates<br />

how clichéd given song lyrics are. However,<br />

while results were reasonable for distinguishing<br />

very clichéd songs from songs that<br />

are fairly free from cliché, it was less successful<br />

with songs that are not at the extremes.<br />

Our method of obtaining human judgements<br />

was not ideal, consisting of two rankings<br />

of ten songs by the research team involved<br />

in the project. For our future work we hope<br />

to obtain independent judgements, possibly of<br />

smaller snippets of songs to make the task easier.<br />

As it is unclear how consistent people are<br />

in judging the clichédness of songs, we expect<br />

to collect a larger set of judgements per lyric.<br />

There were several instances where annotations<br />

in the lyrics influenced our results. Future<br />

work would benefit from a larger, more<br />

accurately transcribed collection. This could<br />

be achieved using Multiple Sequence Alignment<br />

as in Knees et al. (2005). Extending the<br />

model beyond trigrams may also yield interesting<br />

results.<br />

A comparison of number one hits with a<br />

larger collection of lyrics from the same time<br />

period revealed that the typical number one<br />

hit is more clichéd, on average. While we have<br />

examined the relationship between our cliché<br />

score and song popularity, it is important to<br />

note that there is not necessarily a connection<br />

between these factors and writing quality, but<br />

this may also be an interesting area to explore.<br />
