Nick Troop's research
David Bowie is a huge star but his popularity has waxed and waned over the course of his 26 studio albums. There are lots of things that might have influenced this (fashion, the amount of promotion given to the album, the music itself). But it turns out that the words Bowie uses also seem to be related to how long his albums stay in the charts. This is a website where Doctor Nick explores this issue in more detail.
Although people have emotional responses to music, it is not just the music that causes this effect. The expectation that people have about a song can also influence precisely what this reponses will be.
