http://en.wikipedia.org/wiki/Melbourne_Shuffle I wouldn't worry about getting any hard dance music. They'll all probably be too busy smoking ice to worry about busting hectos spins in their phat pants. To classify everyone who listens to Hard Dance as Ice smokers shows how little you know about the dance world. I pretty much only play on the harder edges of dance (not just Hardstyle but anything hard, hard dub, hard house, hard electro, hard techno etc) but I listen to and appreciate all styles as you never know what you will find as inspiration. I have been a shuffler for 4 years and a hard dancer for 14. I have only just joined this forum as a forum should be about helping and sharing knowledge, and having access to a much wider community. I don't believe that it is q place to be slagging any genre or style of dance or to stereotype anyone who does genuinely love that genre. Anything can be shuffled to, shuffle music could be anything so I would be asking the person themselves for a short list of some of their favorite shuffle tracks as that way you can both get an idea of what to look for and the added bonus of being able to drop a few faves of the host.
