title: App idea for creating a playlist using specific paramters (i.e. mood, genre, tempo) using a specific library set
body: <p>I am looking to create an app for Spotify and I was wondering exactly what metadata we are able to access once we have access to Spotify's APIs. The app that I am trying to create would be a playlist creator using music in my organization's Spotify library and is geared towards a specific community. Our library consists of multiple genres of music with a common theme, and I want to provide users with a way to create playlists with set paramters (i.e. genre, mood, activity, tempo, etc.), but I need a way to essentially "tag" songs in our library. Would this be feasible using Spotify's APIs?</p>
