Playlost is a web app for discovering new music through playlists. Playlists submitted to Playlost are analyzed with the Spotify API based on the playlists songs, artists and sub-genres.
This information, as well as the audio features of each track, is used to create a summarized view of the playlist which maps this information into descriptive terminology such as main-genres, mood, style, popularity, and decade of release.
Each playlist analyzed by playlost is retained in a database and can be searched and used as a possible recommended playlist.
The initial playlost database consists of playlists shared on Reddit that were acquired using Pushshift. Every playlist submitted to Reddit with an upvote score above 5 has been included in the playlost database with corresponding information from Reddit including the original post, subreddit, timestamp, submitter, and upvote score.
