echonest-r: working with EchoNest data in R

EchoNest is a music database that Spotify & I Heart Radio are based off of, and allows for interaction via API. There is some really interesting data available, and the functions shown below provide methods for bringing the data into R. I'm building this for my personal use to analyze my music and work on some music data projects. If you have ideas of where to go from here, feel free to suggest them in the issues section, or fork the repo & submit a pull request.

Functions:

• song_audio_analysis.R
• HipsternessPlot.R

song_audio_analysis.R

#####How to Use:

1. Run this code to read the song_analysis function into R

2. Call the function in R

song_audio_analysis("Your EchoNest API Key", "Weezer", "El Scorcho")

Hipsterness Plot
