Band Streaming Links on Google

[spanny]

For those that have music on Spotify, my band released our first album of original music and when you Google our band Name "Six Speed Tranny", various options to stream are listed under their "Listen" section (Pandora, Apple Music, iHeart and Deezer). These appeared automatically after the release (don't ask me how, I'm not technical), but why doesn't Spotify show up as an option, and how would I go about getting that added? Spotify shows up as one of the first options when doing a google search.

Thanks in advance! In general I'm looking to learn more about how to manage our presence on Google, so any additional resources would be appreciated.
