The verses of It's Not Your Birthday Anymore. Its that slightly metallic, wobbly underwater sound. It's pretty unmistakeable. The bends in the melody are too smooth.
I hear what you're saying. I guess I don't know the digital effects (autotune?) well enough to say for sure if his voice was altered after the fact or if he was deliberately modulating his voice in that way. I'm guessing it was his natural voice.
If it was enhanced, well, it was done in a way that wasn't too offensive to my ears. I'd be disappointed in principle but the song doesn't sound artificial and doesn't really alter my original answer: he's singing better than ever.
Anyway thanks for pointing it out.
So, do you think that has anything to do with why he's only performed Birthday once?
