'Cooler Than Me' is already a smash across the pond. How are you coping with fame?
"It's exciting! I'm really grateful for all the blessings that have come my way in the last couple of years, especially over the last two months. At the same time though, I'm not content. I feel like my best music is still ahead of me and I can't wait for everyone to hear it."
What's the very best thing that's happened so far?
"Every day has been pretty cool. I love the fact that I don't have a real job! I grew up making music in my mum's basement, and I used to tell her I was going down there to work and she'd say, 'That's not work, go get a real job!' It took me signing a record deal to change her opinion!"
The track has quite a distinctive sound - how would you describe it?
"It's your new favourite song! You know, it doesn't sound like anybody else's music. I actually recorded it on a cheap microphone in my dorm room when I was still at school. It's about a specific girl at school and a certain type of girl that roams the world. It's cool and I feel like I've made a 21st century album too. Every song is new, exciting and fresh."
How do you go about creating a sound that's completely fresh?
"I try to listen to as much different music as possible - I've always got music blasting in my ears! The reason I became a singer is because of my failure as a producer. I used to go to labels with songs for other artists and they'd always reject me because they didn't suit any artist. I realised the only way I was going to get this sound out there was by releasing it myself."
Were labels keen to sign you as an artist instead?
"I made a CD in my dorm room when I was a student and I put it out on the internet for free, and within a few months people across the States seemed to know the words to my songs! I was blessed to be in a position where I actually picked the label I wanted to be with - a lot of artists don't find themselves in such a lucky spot. I got to choose one that really understood me."
Was it the label who encouraged you to finish University early?
"That was my doing! I signed the deal after my third year at college but my mum forced me to go back to school. For a while I was living a double life where I was at school during the week and flying across the States at the weekends to do shows. I managed to finish my final year in December instead of this May - I was desperate to get the music moving along."
How did your friends react to your music career?
"When I decided to make a mixtape, they thought I was insane. When it was my 21st birthday, I wanted to play my own music and my friends were so upset with me! I used to make music in my dorm and I was forced to adopt a nocturnal lifestyle because it was too noisy to make music in the daytime. It was literally a case of study all day, sleep in the afternoon, make music all night."
Did you become a celebrity on campus?
"A bit! I have to say, they're the people who supported me from the beginning. Without them I wouldn't be sitting in this chair. Some people at college didn't take me seriously at first, but most people gave more support than I could have ever imagined. They spread the word!"
How would you describe your album?
"I guess in its most basic form it's synth-pop/electropop, but it has a unique twist to it. I know it's a bit of an overcrowded genre in the UK, but I honestly just make the music I want to make, and whatever comes out is the sound. The only way to create something unique these days is to follow your personal instincts rather than taking on other people's suggestions."
What artists have influenced your music?
"I was really blessed to come from one of the most diverse cities in the States, so for as long as I can remember I listened to a wide array of music, from The Killers, Led Zeppelin and Red Hot Chilli Peppers to Jay-Z and Paul Simon. The music sounds the way it does because of the environment I grew up in, so it's hard to pinpoint a specific genre."
You recently worked with UK producer Labrinth - will he feature on the LP?
"I've worked with Labrinth, but his song isn't on my album because we're still finishing it. He's a sweetheart and I love him. I heard 'Pass Out' and discovered all his other stuff and loved it. I had a blast working with him. He's the only person I've met who isn't afraid to work as hard as I am. We've done 16-hour days in the studio."
Would you ever consider another stab at producing for other artists?
"Without a doubt. Hopefully labels will take up my offers now, but I'm focusing on making my project as successful as I can first. There are so many artists I love - Lab, Florence, Marina. I love 'Numb' and 'I Am Not A Robot'. The UK music scene has really become the world trendsetter now. The diversity and originality is incredible."
Mike Posner releases 'Cooler Than Me' on November 8. His album, 31 Minutes To Takeoff, follows next year.
