Ok so, clarification question: Did Hydroponikz release this with new lyrics, or did he mash one of his songs and the one from HBMS? Or was it someone else entirely?
He took a portion of "Rock and Roll (Could Never Hip Hop Like This), Pt 2" (an HBMS-medley with a bunch of "songs" and artists following eachother on the same track). He found the instrumental to this track, lengthened it by looping parts of the instrumental, added his own vocals on the looping instrumental, changed over to the full song for the Chester/Mike parts, reverted to the instrumental to do some more rapping and then changed to the full song again, with some added rapping. I believe the rapping lyrics are his own.
