You don't need anything special; no one will know the difference. Everyone just want to have a good time. Just my opinion, hehe.
I am totally ignorant and would appreciate pointers and suggestions on which equipment and disks to buy to add Karaoke functionality to my current audio-video home system, thanks. Any education you can give me in terms of choices of types of equipment, and consequent price and functionality consequences (ease of use, availability of song titles, etc.), would be very welcome. Thank you in advance.
(By the way, I currently have the usual basic home system, with a Pioneer surround receiver feeding a 60" HDTV and Polk Audio surround speakers, fed by Sony CD changer, DVD player, and digital HD cable box.)
