Decoding the Algorithm for Pop Music
fb4f writes "Over at Modplug, they have an article describing a mathematical algorithm to predict if a given song will become a hit or not. Paraphrasing the article, a Spanish company called Polyphonic HMI has made a business out of analyzing song submissions and predicting their "hitability". Here's their description of the algorithm and here's their FAQ. They claim to have predicted the commercial success of Norah Jones through this method. Here's my question (which is not fully answered in their FAQ): if they (music company executives) are currently using the algorithm to screen submissions for their "hitability", can we (people who listen to music) use the same algorithm to reject recycled tunes and encourage originality? I for one, still like the fresh talent and community feel of the tracking scene."
Someone should make an algo to calculate which Slashdot comments will be moderated up to 5. Should be pretty easy...as long as you bash SCO!

Well, I don't know how to tell what songs will be popular. But, obviously, this topic is popular.

The fact that no one understands you doesn't mean you're an artist.
Okay, so far, so good; it sounds like they're saying "good music is good music, and here's a tool for telling whether something is good or not." I'm still skeptical at this point, but it's certainly an interesting idea, and one worthy of study.
But then they completely lose me with this one:
IOW, our algorithm says music is good if it sounds like everything else people think is good right now, and if it's different from current Top 40, it's crap.
They make a high-flown reference to the 36 Plots and other serious attempts at artistic analysis, but that's not what they're actually doing. I do believe that good music is good music, good stories are good stories, etc. I can at least consider seriously the hypothesis that all good art has certain qualities in common, and that by analyzing those qualities we can evaluate a new work's chance of lasting success. But the idea that musicians (or writers, or whatever) can keep pumping out stuff exactly like What's Hot Now and be guaranteed a blockbuster is just stupid.
The correlation between ignorance of statistics and using "correlation is not causation" as an argument is close to 1.
one person's "real" band is another person's manufactured corporate rock. Excess ain't rebellion, you're drinking what they're sellin.
The article states:
"This software will compare the song to a database that contains the "top-30" hit songs of the past five years in order to search for mathematical similarities. The algorithm then assigns each song a score between one and 10. Any song rated more than seven is likely to become a hit."
Now think about this.. use musical eras like the 80's and early 90's as an example because it's reasonably safe to assume this technology didn't exist at that point.
Look at the charts in 5 year chunks, it all sounds the same. In the 80's, everyone either used a synthesizer or had a raging, face-melting solo at some point in the song. Or the early 90's, "grunge" was being pounded into our head incessantly.
It was like that because it was popular. Band X makes it big, and suddenly Bands X1 through X255 appear on the charts mimicing this sound. This seems to happen in, amazingly enough, cycles of 5 years.
Seems to me this software does nothing to show the "hitability" of a song, but rather telling you whether or not it sounds just like what's currently popular, and has been for the past couple years.
Seems about as magical to me as as an algrorythm claiming it can detect boys that like looking at porn.
TITLE OF THE SONG - DaVinci's Notebook
Declaration of my feelings for you
Elaboration on those feelings
Description of how long these feelings have existed
Belief that no one else could feel the same as I
Reminiscence of the pleasant times we've shared
And our relationship's perfection
Recounting of the steps that lead to our love's dissillusion
Mostly involving my unfaithfulness and lies
Penitent admission of wrongdoing
Discovery of the depth of my affection
Regret over the lateness of my epiphany
CHORUS:
Title of the song
Naive expression of love
Reluctance to accept that you are gone
Request to turn back time
And rectify my wrongs
Repetition of the title of the song
Enumeration of my various transgressive actions
Of insufficient motivation
Realization that these actions led to your departure
And my resultant lack of sleep and appetite
Renunciation of my past insensitive behavior
Promise of my reformation
Reassurance that you still are foremeost in my thoughts, now,
Need for instructions how to gain your trust again
Request for reconciliation
Listing of the numerouss tasks that I'd perform
Of physical and emotional compensation
CHORUS
Acknowledgement that I acted foolishly
Increasingly desparate pleas for your return
Sorrow for my infidelity
Vain hope that my sins are forgivable
Appeal for one more opportunity
Drop to my knees to elecit crowd response
Prayers to my chosen deity
Modulation and I hold a high note...
CHORUS
