Hello XxStLxX,
Thanks for reaching out to Apple Support Communities. After reviewing your post, it sounds like you are looking to make your initial Apple Music preferred genre selections over again. We definitely understand that wanting to change up what you listen to is important and we'd love to help. This article can help you make some changes to the way music is suggested: See recommended music on iPhone.
While there is no way to reset it and get back to the “red bubbles” as you called it, you can still change how it suggests music to you. You can select an album, click the ellipsis and select ‘More like this’ or ‘Less like this’. Doing so will change the suggestions to accommodate the new information.
Please let us know if you have follow-up questions about this issue, or if the issue remains unresolved. Have a great day!
