New Releases and Suggestions Playlist

[sabjorn]

Now that we've found an API endpoint for Releases and Suggestions, we can create a playlist of recent releases.

This resource is pagnated, so it should be easy to choose a number of tracks to pull and then keep track of position of user when scrolling in playlist to automatically pull more and append to playlist--think Reddit infinite scroll.

Additionally, an older_than timestamp is used for this API call so the interface should allow users to input a date range and query against that.
