* Create a string combining `{SPOTIFY_CLIENT_ID}:{SPOTIFY_CLIENT_SECRET}` (e.g. `5n7o4v5a3t7o5r2e3m1:5a8n7d3r4e2w5n8o2v3a7c5`) and **encode** into [Base64](https://base64.io/).
If you want a distinction between the widget showing your currently playing, and your recently playing, you can hide the EQ bar when you're not actively listening.
Remove the `#` in front of `contentBar` in [line 81](https://github.com/novatorem/novatorem/blob/98ba4a8489ad86f5f73e95088e620e8859d28e71/api/spotify.py#L81) of current master, then the EQ bar will be hidden when you're in not currently playing anything.
