Two great arti­cles on cur­rent research into how artists and songs become hits:

Group Think looks at research pre­dict­ing musi­cal hits using “geo-aware query strings” from file-sharing net­works such as Gnutella.

The geo­graphic loca­tion of an emerg­ing artist is the key to pre­dict­ing their suc­cess […]. “If an artist has the poten­tial to be suc­cess­ful, peo­ple will first start notic­ing them in the small geo­graph­i­cal area where they live and per­form.” In fact, a poten­tial pop star will typ­i­cally enjoy thou­sands of down­loads a day on a local level, while remain­ing rel­a­tively unheard of on a national level. A large diver­gence between local and global pop­u­lar­ity, called the Kullback-Leiber diver­gence, is a strong indi­ca­tor of star poten­tial. The algo­rithm mea­sures the K-L diver­gence to pro­duce a short list of poten­tials, of which 15 to 30 per­cent will go on to reach national pop­u­lar­ity within weeks.

Tak­ing a dif­fer­ent approach, The Anatomy of a Hit Song shows that what makes many of us like a cer­tain song isn’t its sound; it’s the ‘out­side influ­ence’ of our peers lik­ing the song.

While [the researcher] could pre­dict which songs would be pop­u­lar after an ini­tial round of feed­back, he said it’s ini­tially dif­fi­cult to guess which songs will become pop­u­lar and which will be despised strictly on their own mer­its. He cites the per­for­mance of the song “Lock­down” by 52metro, which ranked right in the mid­dle among the 48 avail­able tracks by lis­ten­ers who had no social con­text. How­ever, in two sam­ples sub­jected to out­side influ­ence, it came in first place in one trial and 40th in the other.

As the arti­cle states, these find­ings aren’t strictly con­fined to music; the the­ory likely applies just as much to books, movies and TV shows.
