Seems there is a glitch. When you “Go to artist” from the song that’s playing, it will only bring the first artist mentioned. Now, if you look up the song in the playlist and hit the 3 dots, you will see it displays “view artists”, and all of the artists for that song show.
Seems the spotify team missed this one. Feels as a vlookup that only shows the first result 😛 Hope they fix it.
