I particularly love this sour addendum to the article (hooray for user-editable articles)…

"Jim Tremayne - an editor of the DJ Times magazine - says that this isn't a big thing for the DJ world. According to him, this method takes too much effort for an amateur. Not everybody is able to figure iPods out. DJs offer more expertise and do more than just playing records, Tremayne says."
