I listened to a video on You Tube that compares the 2 songs. I think the only sounds that are the same are the drum beat/cowbell in between verses. So I don't know.
I am sure people in the music industry have heard so many songs in their lifetime, that when making new music this can happen by accident. I just don't think it was deliberate. But obviously the court did.
Also, I've heard so many songs over the years by various artists that sound like they have similarities to other songs, but no lawsuit ever came out of them.
