A couple of crowd chant/song mysteries

1) Why has Golovkin's team adopted 'Seven Nation Army' as his song, when there's nothing chantable about his name unlike Anthonys Joshua and Crolla? Or even Enzo Amore from WWE for that matter. Surely it'd make more sense for him to come out to something badass like Vitali did? Goddamn I hate that piece of shit song... 2) In Ricky Burns' last few fights, the lager louts in the crowd keep chanting something that sounds way too much like Michael Sembello's 'Maniac', but it probably isn't. I keep hearing "He's a Maniac, Maaaaaniac, aaaaahhhhh!" Huh? Bunch of Jocks...
