How are you supposed to pronounce "Macklemore"? - awful.systems

I’d been pronouncing it as “Mackle-more” but then I watched Todd In The Shadows’ new video about him, and I swear he pronounced it “Mack-le-more” for half the video, and now I don’t know which one is the real pronounciation and which one is the joke. I have no strong feelings about him as an artist one way or another but I’d feel like a dick if I’d been inadvertently clowning on him for over a decade.

For the reddit-shy, link is a reddit thread from Macklemore announcing a new music video. Commenter asks how to pronounce it. He says “Mack-la-more. Should have picked an easier name”. Another commenter asks why the kid in Thrift Shop says it the other way. No response.
Thanks, didn’t think to explain
Well, shit. Sorry Mr Macklemore :(
