I think the leaked stuff is before they changed the songs. They had to go back into chango to re write and re work some songs because sumerian didn't like them. Or so i've been told
Probably like "hmm, can you guys make it a bit less shit?"
Honestly that leaked version was just bad from all angles. Having said that, they have potential to be something more than just an Aussie Asking Alexandria cover band so I hope the rewrites actually come out sounding better than what they are now.
As for MMF, aside from Dennis, rest of the band sounded like they could actually be decent (drummer and the other guitarist especially). Dennis though, back in his youtube days was a huge arrogant scumbag just from the way he treated anybody who didn't get wet over his autotuned covers.
