They're not a plant, that's Bliss N Eso, Aussie rap group. Been around for a while, they even used to actually post on

I met one of them on there before they dropped because he was one of the only Aussies on there. This was prob 2003 or something, maybe a bit earler than that even.
When I saw the kid drawing the wings and shyt at the start I thought it might be them but wasn't sure until the second verse, dude has an Aussie accent. The first guy was born in US but moved to Oz when he was young.
I don't like their music that much but they are pretty popular down here.
