Congratulations on the album being number one in the midweeks.
"Yeah, it's looking good at the moment so I should probably take a screen-grab. Sadly, I'm pretty sure I can't sustain those kind of sales through the week even though it's a f***ing brilliant album and everybody should buy it at least twice."
What would you say to someone who's on the fence about buying the album?
"Well, if they've heard 'Dance Wiv Me', 'I'm Not Alone' and 'Ready For The Weekend' and still aren't sure, I'd say to them that I've spent so long making sure this isn't a s**t album. I saw this album as my last chance basically. I know that I'm good at music and I really wanted to make something that's as good as I know I can be. This album is kind of the ultimate showcase of me - if you don't like this album, you don't like me, and I couldn't have said that about the last album."
The Guardian gave the album a pretty nasty review - and you Tweeted about it accordingly. How are you feeling about that now?
"After The Guardian gave me one star for my first album, two stars for the second one is a step up. Perhaps by the time I see out my five-album deal I'll have a five-star review on my hands? To be honest with you, I went through that guy's reviews and he's the sort of guy who rates something based on whether it's cool or not and based on certain factors that aren't to do with music. He knew what he was going to give my album before he listened to it. He couldn't give it one star because there are two No.1 singles on there and that would be ridiculous, so two stars was the minimum he could give. It wasn't that I was shocked by the review, more that I was disappointed."
Do you have a thick skin when it comes to reviews?
"No, I have an incredibly thin skin about this kind of stuff which is why I shouldn't read my reviews. But I spend a lot of time in front of my computer because I make music all day and it's the tool of my trade. It's all too easy to check what's going on online."
You've collaborated with Dizzee Rascal again on his new single 'Holiday'. Why do you think you work so well together?
"I like Dizzee because he's not frightened to try things that are a bit risky. I can do unusual things on a track and after a few listens, he'll say, 'I really like that'. A lot of people don't want to take those risks. The way he's set up on his own label, he doesn't really have to answer to anybody. Once he decides something's good, it goes ahead and happens. That's well refreshing because I've worked with some big, big pop acts and you literally have to go through tens of people before anything gets approved. That can get frustrating occasionally, though it's all for the greater good."
How do you decide who you want to work with?
"I like people who have really good voices and I like people who I think are popstars. I always thought of Dizzee Rascal as a popstar - he may not have had any pop records to begin with, but in terms of personality he was clearly a popstar. Katy Perry's an amazing popstar too and when I heard she wanted to work with me I was like, 'What?! F**king definitely!'"
Have you locked down any time with her yet?
"Yeah, I'm going into the studio with her in December. She wants to go in with no pre-planning but I'm the sort of guy who wants to turn up with nine or ten instrumentals and play them to her to see what she thinks. I think I'm going to do that regardless and see what happens. I'm looking forward to working with her - she's a normal person and she's not up her own a**e the way a lot of these American popstars are."
Have you got any other collaborations lined up?
"Not really, but I did get an email from Robbie Williams the other day, which was just mental. He sent me a picture of him, the Spice Girls and Boyzone wearing ridiculous '90s pop outfits and said, 'Please stop being a popstar because you're making us all look bad'. I thought that was a really nice thing to do."
Did you reply?
"I did. I said I was looking forward to his record and it's always nice when a genuine pop superstar comes back to show us how it's really done. His new album's going to be amazing. I can't wait for it."
Finally, you've been slating lime marmalade on your Twitter. What's wrong with it?
"Oh, it's too bitter! I thought it would be sweeter than it was. When I worked in Safeway one of my jobs was stacking up the marmalade and I'd always put up the lime marmalade and think 'That looks really nice'. It was only the other day, six years later, that I actually got to try it. It was so horrible it ruined my lunch. I had a really nice poppy-seed bloomer and some Anchor spreadable butter so it was all going really well until I put on the lime marmalade. It kind of tasted like bleach. I can understand why lemon marmalade would be OK, but lime marmalade's a step too far."
The album Ready For The Weekend by Calvin Harris is out now.
