I've read numerous articles on this and have come to the conclusion that while the arrangements were similar(aka "groove"), the lyrics and melody were definitely not copying Marvin Gaye's "GOT TO GIVE IT UP". I'm getting tired of copyright infringement suits that stretch the definition of such infringement. Should it get to the point where if a composer uses a rock rhythm with the same BPM as a 20+ year old song of which they may not even be aware that they should be sued? As it is now, original music - at least where I live - has a rough road for getting exposure. Most of the big concerts that draw, are acts that are 20+ years old and no longer charting. It's intimidating to think the if some old fart artist notices that you have a few chord progressions or rhythm sections in your original tune that are the same as a song they wrote in another era but are lyrically and melodically different, they still can sue.
