Crunching the Math On iTunes

markmcb writes "OmniNerd has posted an interesting article about the statistical math behind iTunes. The author makes some interesting observations concerning the same song playing twice in a row during party shuffle play, the impact that star ratings have on playback, and comparisons with plain old random play (star ratings not considered)." From the article: "To test the option's preference for 5-stars, I created a short playlist of six songs: one from each different star rating and a song left un-rated. The songs were from the same genre and artist and were changed to be only one second in duration. After resetting the play count to zero, I hit play and left my desk for the weekend. To satisfy a little more curiosity, I ran the same songs once more on a different weekend without selecting the option to play higher rated songs more often. Monday morning the play counts were as shown in Table 1."

    what the fuck was that stupid comment?

    it wasn't funny, it wasn't a troll, it didn't even make sense. I was hoping i'd find a gnaa reference in there...

    Dude, you need to find another buisness.

    Sell your "Christian" music store to some bible thumping fool and do something else.

    Because if you assaulted my kid, I would own you. At the very least you would lose your buisness, at the very worst you could be complaining about how iTunes ruined your buisness to your new serial booty bandit cellmate who would think your ass was cute.

    See, i just download it and take it. If i like it i'll listen to it again. I wouldn't pay anyone though, that'd be a false economy. Why pay for what I already have??

    wow.
    So let's see; you dont sell all kinds of music cause you got problems with rap and manson, and thats cool really. You just cant blame people if they'd rather get what THEY want, the way they want it. If you dont have it, its your fault in the first place, and dont come telling me that families are getting family music off the net cause they arent. You are talking about young punksters, and stoopid ones since they even talked in front of you (and i doubt your story is true)

    You would like a national blacklist of potential customers. I would like a blacklist of crap shops like yours to make sure you go bankrupt, cause you dont love either music or music listeners and deserve to get out of business as the new distribution model grows in front of your blind eyes.

    Enjoy it.

    I really wish I had a slashdot name, but for now, you can call me AC.

    How can you have any doubt in your mind as to why your business is failing? You bully your customers(a grown man resorting to physical measures on a teen? Real fucking classy) and you call your store a 'clean' place. I'm sorry the music economy is hurting you right now, but the nature of the business has changed. This article is about legal downloading, which is what you should really be worried about.

    And did you ever think that maybe the nice, clean looking people who come into the store and buy the CDs without saying anything might go home and burn copies for all of their friends? Think about that, next time you threaten away a sale.

    you dumb fuck they evensaid that apple itunes sales way outstrip internet piracy and that piracy is falling and most people would rather just buy the song. If your business is being ruined by a completely legal competitor, too bad. Maybe if you stopped blaming "pirates" for all your lil problems you could focus on stuff that really matters and turn a profit. Or you could sell more than your lil kiddy carebear stuff, as thats not really what is popular, so if you wanna make money it would be a good idea to stock popular things.
