Analysis of playlist corpus

Gather information about the available playlists and their characteristics (distributions, basic features, representations).

This issue involves (but might not be limited to) following steps:

• Exploratory analysis (a lot has been summarized by Spotify already but making it easier to access and more visual)
• Feature development (Is there additional information in dataset that can be leveraged? (Playlist title, Playlist description, How often a playlist was changed, Popularity of songs / playlist)
• Thoughts on song and playlist representation (foreshadowing encoding, latent feature models, word2vec, co-occurrence, and statistical models)
