In that case, the baseline was directly ripped off, it wasn’t just “sounded similar”, it was an actual sample.
If sampling to create new art were better protected, then cases like this wouldn't even come up. The documentary "Good Copy Bad Copy" was talking about this 12 years ago
Yeah I think we're long overdue to reevaluate what copyright means in music. I think it should be much closer to how we treat fashion where anything but a direct rip off is 100% fair game (and that is even more about trademarks because the actual design can't be copyrighted).
