I've never heard of O Magazine, and ended up using Google to try and find it, after first guessing, I think, Desire Magazine and Power Magazine, both of which turned something up on Google as well. I also Googled Euro Magazine but it didn't turn anything up.
I have no idea what bubblegum pop or power pop are.
I completely failed to solve the puzzle at all because I didn't know of O, Fortune, or Mad Magazine and have never actually watched a Bond movie. I haven't heard of power pop but knew of the other three types and probably could have gotten that. So you're not alone, I actually did worse than you, only getting the yellow row.
