When you are selecting the genres for your campaign, you may want further clarification on what each genre sounds like.
Using EveryNoise.com is great for this. The site has a full list of every Spotify genre. If you click on any genre it will begin playing a playlist with songs that Spotify has categorized in that genre.
This allows you to get familiar with any genre and determine which are a fit for you.
Below is an example of how to use EveryNoise when setting up a campaign:
1) You see a genre you’re unfamiliar with (i.e. “chillwave”)
2) Go to the EveryNoise's List Section and search the page for the genre
4) Click on the genre and Listen to The Spotify Playlist That Appears to determine if this genre is a fit.
