A greenlist is a list of approved accounts that can use your content for services that utilize Content ID. If you want to greenlist your own account, or grant access to others, you need to submit a greenlist request.
Too Lost currently allows you to create greenlist requests for the following services:
SoundCloud
YouTube
TikTok
You may need to greenlist your own account so that you can publish your own content. If you delivered your release via Too Lost, you may receive a copyright notice (do not worry if you do, it doesn't damage your account standing. It is just an email alerting you that the rights to the track are protected).
You can add your account to the greenlist request form and re-upload the track on the blocked platform in 1-2 hours.
