'How can I make this sound more like Madonna?'

Justin Timberlake was interviewed for Hollyeood Daily People and of course was asked a few questions about his upcoming work with Madonna:

You worked on Madonna's new album with Timbaland. In what direction did you take her?
Basically, our job was to re-invent her sound. My thing was producing her vocals, really experimenting with rhythm. Everything she does with rhythm is straightforward. What I do is more staccato and R&B. So the challenge for me was writing songs, then saying, 'How can I make this sound more like Madonna?' I'm a big fan of her first album. So my mission was to write a modern-day 'Holiday.' I wrote a cool house record for her called 'Miles Away' that I think is a smash! She sounds great on it.
So is it an R&B Madonna?
It's an R&B/pop/dance record, but it´s still Madonna. Her voice still sounds like she's 18 year old! It trips me out that she's 49. She´s always been rough and tough. Her last couple of records, she's like, 'Rrrrrrr!'
How did she react to your ideas?
A couple of times I pushed her in a direction where it took a minute before we saw eye to eye. Her approach was, 'Well, I just haven't done that.' And I was like, 'Yeah, that´s why you should do it.'
So did you teach Madonna how to beatbox?
(Laughs) No, no. We left that to me and Tim.
