Help Me Erin D?? I have no idea what I'm doing

Ok so like I know the song and I get the cute bracket jumps to ERIN ERIN, but these shoes are so utterly cumbersome!! I had no idea there were even dance games in the Czech Republic. Machine volume was opposite of the pump, which was VERY low, this was VERY loud, liter the loudest machine I've ever encountered including my own ITG setup. I think this is at Game works or something. I'll get the arcade name if someone is interested.
