Updated list of what happened to the music artists. Part 1 · 7:29am Oct 31st, 2016
Just a random list cause I'm bored. This is strictly limited to activity on YT and I'm only considering an artist to be inactive after more than a month without new mlp related content. Note that I have only included single artists, not collabs or bands. Artists who have changed names will habve their new name in brackets beside the original name. I will only include artists on YT here, so this is not a comprehensive list. inactive only means they haven't uploaded content.
