So, after 3 years, I finally got tired of the same music on Slacker, and added Spotify. During the past 3 years, I had added a bunch of favorite artists to my Tesla Slacker app. I had assumed that when I added Spotify, these favorite stations would not work in Spotify, but remain only Slacker stations. But today I tried it, and, from the music that followed, it was apparently pulling the selections from Spotify, not Slacker. Am I imagining this, or is it really happening? Did all of my Slacker stations migrate to Spotify? If so, Kudos to Tesla.
