工程师Ari Vaniderstine今天早上在推特上发布了一个名为Nelson的小故障项目的链接，该项目是一个浏览器应用程序，Spotify用户可以在推荐API中处理各种输入，并**自己的算法生成的播放列表。

如果您拥有Spotify premium帐户，您可以从一个长长的列表中选择一种类型的组合，出于某种原因，其中包括“流行电影”，但不包括说唱，然后使用为其他九个“音频功能”提供的滑块口述播放列表的其他参数。Spotify的开发者博客上介绍了这些功能：

Acousticness: A confidence measure from 0.0 to 1.0 of whether the track is acoustic. 1.0 represents high confidence the track is acoustic.

Danceability: Describes how suitable a track is for dancing based on a combination of musical elements including tempo, rhythm stability, beat strength, and overall regularity. A value of 0.0 is least danceable and 1.0 is most danceable.

Energy: Energy is a measure from 0.0 to 1.0 and represents a perceptual measure of intensity and activity. Typically, energetic tracks feel fast, loud, and noisy.

Instrumentalness: Predicts whether a track contains no vocals. “Ooh” and “aah” sounds are treated as instrumental in this context. Rap or spoken word tracks are clearly “vocal.” The closer the instrumentalness value is to 1.0, the greater likelihood the track contains no vocal content. Values above 0.5 are intended to represent instrumental tracks, but confidence is higher as the value approaches 1.0.

Liveness: Detects the presence of an audience in the recording. Higher liveness values represent an increased probability that the track was performed live. A value above 0.8 provides strong likelihood that the track is live.

Speechiness: Speechiness detects the presence of spoken words in a track. The more exclusively speech-like the recording (e.g. talk show, audio book, poetry), the closer to 1.0 the attribute value. Values above 0.66 describe tracks that are probably made entirely of spoken words. Values between 0.33 and 0.66 describe tracks that may contain both music and speech, either in secti*** or layered, including such cases as rap music. Values below 0.33 most likely represent music and other non-speech-like tracks.

Tempo: The overall estimated tempo of a track in beats per minute (BPM). In musical terminology, tempo is the speed or pace of a given piece and derives directly from the average beat duration.

Valence: A measure from 0.0 to 1.0 describing the musical positiveness conveyed by a track. Tracks with high valence sound more positive (e.g. happy, cheerful, euphoric), while tracks with low valence sound more negative (e.g. sad, depressed, angry).

它不太管用——我加入了布鲁斯、R&amp；B、 雨天，歌手，词曲作者，和灵魂，并得到了两个芒福德&amp；儿子们在上面唱歌——但在随机滑动酒吧，观看卡莉·雷·杰普森和詹姆斯·布朗之间的节目《恐慌》切换，会让人感到满足。

我尝试了很多不同的组合，得到了很多糟糕的建议，但仍然玩得很开心。你还做了什么？和Nelson一起**一些半人半算法的电子人播放列表。
