I like these new clearly defined rules concerning the use of vocal samples. Here's some thoght's that came to my mind.
SWC can be considered more broadly as a "music making" competition or more precisely as a "song writing" competition. I guess it's up to Mr Fox to decide how he wants to define it.
If we think the SWC as a "song writing" competition, then we are using juridically defined words. Legistlation tries to answer the question: if our submission is played in Spotify, YouTube or radio, who is entitled to get the money for that? And the answer probably is: copyright covers only the melody and lyrics of a song.
And even if we prefer to think SWC as "music making" competition, we must be careful with issues related to copyright issues.
Here are some definitions:

"Songwriting is the process of writing the lyrics, as well as the music composition or melody to songs."
"The person who writes the lyrics is a lyricist and the one who writes the music is the composer."
When we are listening music, there are also other issues that are separate from songwriting, but that are still important. For example: the arrangement, mixing, mastering, performance (players, singers) etc. And when it comes to music that was made after the birth of rock'n'roll, it's quite normal that the songwriting (=copyright) part may be quite poor, but the arrangement and performance turns the song into a hit. But still, the money of the radio play goes to copyright owner.

"The financial rewards of an arranging career are limited. Arrangers are paid per job, and the fee isn’t huge. If they keep working and get jobs every week, they can pay their mortgages. Arrangers receive no royalties unless they write an arrangement of a public-domain work."
So, as "music makers" we have to acknowledge the importance of sound, arrangement, performance, melody, lyrics, etc. But if we happen to make a radio hit, money goes to the songwriter (melody, lyrics) and publisher.
So, when it comes to submissions to "song writing" competition, I think it's quite natural to expect that contestant (person or team) is also a copyright owner of the submission. But when it comes to voting process — although I personally concentrate almost entirely into songwriting part — it's totally ok for me that each and every person emphasize whatever aspect of the music making they want to emphasize.
