Calvin Harris doesn't do remixes for money, and says all his collaborations come about as a result of favours and swaps.
Calvin Harris doesn't do remixes for money.
He told The Guardian newspaper: ''I can't remember the last time I did a remix for actual money. For me I try and get a good swap.
I remixed 'Spectrum' for Florence in exchange for a vocal part from her.
''It's old-school but it worked out beautifully.
''Every remix I've done in the last couple of years has been a swap for some other musical thing. As for money, that's not even a factor - you could not buy me to remix one of your records. But if it's something I wanted to do, I honestly couldn't care less if I got £5 or £50,000.''
Calvin, 28, also prefers to record with female singers, as their voices work better on dance tracks.
He added: ''They're always at the perfect frequency to play in a club. A good, soaring, high-mid female vocal bounces off the walls nicely, and it doesn't interfere with the bass or drumbeat. It's basic science. A man's voice is likely to interfere with the bassline which is why you don't hear many classic dance tracks with a male lead.''
Calvin's latest album, '18 Months' is out now.
