I don't have a problem with the image being joked on, so long as it's done well. I wouldn't call it a "rip-off". Think about all the stuff you've seen where people have riffed on Glaser's Dylan poster where he has multicolored hair or where people have done something with the vision start that starts with a big E. Yeah, most of it's fucked out but if it's good, it's good. I feel this one is 45% of the way there.
this rip-off has been done SO many times in the last five years it's ridiculous. The turntabilists got a hold of it first and then hip hop and then on down the line.
In genres of music that are not typically represented on GP, this is akin to that clip art octopus or birds or something.
That being said, I still like it.
