I have nearly 200,000 songs to D.J. with in music videos, MP3's and karaoke, all on a 4 TB hard drive so there is no worry of having lost WiFi connections or dropped cell phone signals which happen to those unprofessional DJ's using smart phones to do the job. I get over 250 new music videos every month to keep current for TOP 50 charted songs in POP, COUNTRY, URBAN, ROCK etc, so I'll have the songs your guests will be requesting and want to dance too. Here's a list of the most popular D.J. songs by decades compiled in 2020!
