I'm not sure what you are trying to say here - that this website is comparable to Spotify? Even if you are talking about just the "core experience", this example supports the opposite argument that you are trying to make.
Spotify has the licensing rights to songs and I don't have the business acumen to go about getting those rights, so I guess I could make Pirate Spotify and get sued by the labels for copyright infringement, but that would just be a bunch of grief for me which would be not very fun and why would I want to screw artists out of getting paid to begin with?
i think ive detected the root cause of your problem.
and, funnily enough, it goes a long way to explaining the experiences of some other commentators in this thread on “vibe coding competitive SaaS products”.
