The first time I came across an Ed Sheeran song midway through, I thought it was Marvin Gaye. Apparently someone else noticed as well. https://www.youtube.com/watch?v=dSCx16bVYJ4
There's a pretty good writeup on the Zep verdict, and why it was the right decision. Essentially, Zep was influenced by Spirit, who may have been influenced by another artist twenty years prior, who may have been influenced by another composer who lived 350 years ago.
Quote:
If Led Zeppelin ripped off Spirit, then both bands ripped off Granata—and Granata's work is in the public domain, as are any other examples of this musical idea that precede him. So even under the far-too-restrictive set of rules that make up modern copyright law, everyone is free to do as they please with this age-old sequence of sounds.
"if the bar for [proving] copyright infringement gets lower, then the risk of getting sued gets higher—especially in the world of pop, where music tends to be both highly formulaic and highly profitable. Greater risk means higher cost, which means that only the companies with the deepest pockets and the best lawyers can afford to bring new music to market." A loss today would have been a loss for bands with far less cash and influence than Led Zeppelin.

Paul's Boutique could ever be made today as a result of changes to copyright laws regarding sampling; the cost would be astronomical. I'm all for protecting intellectual property, but there has to be some leeway for creative reimagining of existing work.
