Android/iPhone: Sometimes, the best way to discover new music is to dig in at random. Case in point, Playlist a Day is an app that will send you one themed playlist, every day, so you can find new stuff to listen to.
Playlist a Day uses the massive repository of playlists on Playlists.net. Every day, an editor-curated playlist is kicked over to the app, where you can listen to it in app or import it directly into Spotify (you’ll need Spotify Premium to use it though). Sure, Spotify’s built-in Discover Weekly playlist is great, but if you’re down for a little more randomness in your music discovery, this is a fun approach.
