Getting a random or filtered song from the entire Spotify library

[timmyvc123]

My Question or Issue

I'm working on a an app that integrates the Spotify Web API.  was wondering if anybody knew how to or had any ideas on how to get a random song from the entire Spotify library using the API. Or instead of a totally random song, a song that the user gives filters for like "songs on in the rick genre", "songs that were today" or "songs with less than 1,00 streams",
