Having a chat with the BBC, he 'explained': "She will decide how many will be on her album and I don't know how many that will be."
"[We] just started collecting ideas. I didn't know which song would be for her," he continued. "If she didn't like a song I'd probably use it for myself or maybe she'd sing it for me. We just made music."
How far is it along on the scale from Zedd to Lady Gaga, though?
"I feel it sounds right in the middle between Zedd and Lady Gaga."
He also wanted to clarify comments he made about the album recently and how it's nowhere near being finished.
"There's been an interview where someone basically took a part of what I said and turned it into what everyone would love to hear — which was not true."
So now you know.
