How does filming “song writing sessions” help here? A songwriter could be grocery shopping and hear a tune they like and copy it. I don’t understand how filming just sessions will protect anyone.
I think the key is the progression. If you see how a melody is formed, then it’s more likely to be organic. If you are just copying something, there is less of a progression as when you’re video recording, it’s already almost “done”.
Maybe if you were a mid-19th Century German composer it worked something like that. But that's just not how most songwriting works.
E.g., according to Mark Ronson:
1. Amy Winehouse casually spoke the following sentence in a conversation with Mark Ronson: "They tried to make me go to Rehab
but I said, 'No, no, no.'"
2. Mark Ronson said, "That could be a song."
3. They went to the studio where Amy Winehouse played a 12-bar blues chord progression on the guitar and sang those lyrics (using a simple pentatonic scale).
4. Mark suggested to speed it up and do a throwback Motown-era arrangement.
5. Done.
Unless they recorded their entire conversation, all you'd get is Winehouse sitting down with a guitar and singing the entire hook of the song.
If anything, anxiety-fueled "song formation" recordings will just cause songwriters to waste time going in the wrong direction. That is, they'll take their ready-to-go phrases or sub-phrases of music and sing fragments into the mic, in an order that seems as if they are constructing what they already have formed in their ear.
That doesn't answer the question. You could be out buying groceries, hear a good tune, and then pretend you invented it in steps when you get back to your studio.
Just like we pretend we figured out the tortoise/hare algorithm for finding loops in linked lists at interviews.
