Many parents are no doubt familiar with their teenagers' musical tastes. But very few are probably inspired enough to launch an experiment into them.
"I listened to some of the music my oldest teenage daughter is listening to. And I was surprised at how different that music was from what I used to listen to." Natalia Komarova, an applied mathematician at U.C. Irvine.
"Since I'm interested in evolution in general, and a mathematical description of evolution, I thought studying the evolution of music would be a good idea."
Komarova and her team analyzed half a million songs released in the U.K. between 1985 and 2015 using online databases that describe songs' musical characteristics, like rhythm, mood and danceability. "Here's a song that was high on the charts in 2014 that has high danceability: "Shake It Off" by Taylor Swift. (CLIP: "Shake It Off")
"Here's a 2014 song that has a low happiness index:"Stay with Me," by Sam Smith." (CLIP: "Stay with Me")
Overall, they found that songs had become less happy over the 30-year span; as well as more danceable, more relaxed—and more likely to have women behind the mic.

But the big hits bucked a number of those trends. "The behavior of successful songs looked almost like a separate species of songs. They have quantifiably different features, their own little trends."
The hit singles were happier than the norm...almost a throwback to earlier times. And even more likely to be sung by women. The details are in the journal Royal Society Open Science.
Komarova's team was also able to predict a song's success, by judging only its musical qualities, about 75 percent of the time. "It turns out that you can predict the success to a certain degree of accuracy only based on music, so to me that's very positive. It means that music matters, for song success—it's not just money."
Proving that, at least when it comes to their musical tastes... the kids are alright. (CLIP: "The Kids Are Alright")

毫无疑问，许多父母都熟悉他们十几岁孩子的音乐品味QQN-7Jgx3B8slL。但很少有人会从中获得启发，并展开实验~vWwrWZH629-[s。
“我听了我10几岁大女儿正在听的一些音乐q.I+-PCa4FMa**VoN82.。令我惊讶的是，这些音乐与我以前听的音乐差别非常大YZ|#!6XRyQ,yf]。”加州大学欧文分校的应用数学家纳塔莉娅·科马罗娃说到%uD*)6;X+T2H!。
“因为我对一般进化和进化的数学描述感兴趣，所以我认为研究音乐的演变会是个好主意Gg~mdK4inV。”
科马罗娃和团队分析了1985年至2015年间在英国发表的50万首歌曲，用在线数据库描述这些歌曲的音乐特征，比如节奏、调式和舞蹈性等-T50Lx-=[!^|ZI)zK。“有一首歌舞蹈性很强，位列2014英国排行榜前列：这首歌是泰勒·斯威夫特的《摆脱》hN+xugK-k#h|zc。”（背景音乐《摆脱》）
“2014年发行的另一首歌幸福指数很低：这首歌是萨姆·史密斯的《和我在一起》Emh_gd@,,ZXGPd83。”（背景音乐《和我在一起》）
总体来说，他们发现在30年的时间里，歌曲的幸福程度降低了，但变得更具舞蹈性、更轻松随意，并且更有可能由女性演唱了U=@5ct,xcgtMs.。
但是，热门歌曲与一些趋势背道而驰Og.%t@#rHH。“从成功歌曲的表现来看，它们好像是一种独特的歌曲类型cU|f6Qb*UnhTUt)5|i4。它们具有不同的可量化特征和自己的小趋势*j3RN%B=s,。”
热门单曲比普通歌曲更欢快，这几乎回到了较早期歌曲的特点FS~UYw^M80#~%dQ(0(。而且更可能由女性演唱cVbftZ1%Us@E(BlIfRu。这项研究的具体内容发表在《英国皇家学会·开放科学》期刊上ZDLGnYcb(141Weg7+g。
科马罗娃的团队仅凭对音乐品质的评判，就能预测歌曲是否能成功，而且预测准确率高达75%左右OJT0yau;q3r9!^Un0yA。“结果表明，你可以在某种程度的准确性上，只凭音乐来预测歌曲是否会流行，对我来说这具有积极意义mBondDDjxUa3。这意味着歌曲能否成功不只与投入的金钱有关，音乐也很重要#bS-FPkI;tp@。”
这也证明，至少在音乐品味方面，孩子们都很好N]C5dYFC3S。（背景音乐《孩子们都很好》）
