Artists share links to their music constantly, but broken links show generic error pages. A service could let them customize 404 pages with merch links, socials, or alternative listening options.
Build a simple CMS where artists upload their branding and redirect rules. Host their custom 404 pages on a subdomain or offer a snippet for self-hosting.
Labels and indie artists pay for better fan engagement when links break. Charge monthly based on traffic volume.
Start with a basic template editor and manual domain setup. Later add analytics and smart redirects.
The risk is platforms like Apple Music adding this feature natively.
