I absolutely love this song, though I can respect anyone who finds the way he says "Vulnerable" to be too distracting. Yes, obviously it would be four syllables if saying it correctly, but he could just swallow the "e" a little less and make it work. VULN-erA-BLE instead of VULN-RA-BLE. It would be nice to not even speak English so this would not bother me.
On the commentary given by Neil and Chris on Yes, they state that this song is written from someone else's perspective, who is famous. I like to think of it as Kylie singing the song, around the time she was fighting cancer.
