Link? I don't remember any quote along those lines. Plus, his debut performance was quite good.
Right, I too would like to see a link, as I don't recall hearing anything about how Camden was personally experiencing his fp. It's widely known that Jason Brown voiced some misgivings at first about his fp music, but then he later warmed to it, despite the fact it was never a strong program for him all season.
OTOH, I adore Camden's WSS and he got high pcs for it.
Let's not forget, Max Aaron won nationals with WSS and placed high at worlds with it, and he is not exactly a "sophisticated" skater.

I doubt that is jinxed music
The idea of WSS for Camden maybe was a good one, but on the ice it hasn't worked for him all season long, as I discussed in a previous post. I agree with
@jiejie that the music is difficult to skate to for some skaters. And Camden is a very musical skater, so it's a conundrum. Something seemed off with the pacing and/or the layout. He did not ever seem comfortable with the program, IMO. Maybe it also has something to do with shortened programs and how the program was put together. Maybe he never felt at ease with hitting the musical nuances and trying to stay on the beat while getting in all the elements consistently, which led to pops, etc.
Yeah, I liked Camden's FS too. It was nice to see him try a different style.
It's cool to stretch and try a different style, but if it's not working, that fact should be acknowledged and resolved.
... music that seems to be the Kiss of Death as far as winning top competitions goes. I'm positive WSS was on that list. Maybe it's just too difficult to skate WELL to for most skaters
Yes, it seems to be difficult for skaters, as it requires a good cut, and a program layout that works. Plus, the music is character and theme driven, which is also challenging. As I mentioned earlier, perhaps Edward Villella could have been brought in to help Camden work on the musical and character nuances (Villella danced to the original Jerome Robbins'
West Side Story Suite for New York City Ballet).
