The singer, who recently released his debut album Replay, also admitted that people probably think he is mad because he is always singing to himself in public places.
"I came up with a hook in a Subway bathroom for a song called 'There You Are'," he told the Daily Star.
"It doesn’t matter where I am, I just record straight into my iPhone. They probably think I’m crazy singing into my phone in public spaces."
Iyaz was recently confirmed to play at this year's T4 On The Beach.
