For DJ events, Sound Machine Productions has a huge collection of music dating back to the 1940s! This collection is comprised of all-time hits through decades! But it doesn't stop there! Sound Machine Productions is a proud member of Promo Only! Promo Only brings us the hits at almost the same time that the radio stations get them! This way we get all the hits when they're hot, and while they're on the radio (not when the CD finally debuts). Browse through this playlist section and the "hot charts" section which contains the hottest song charts from Billboard and the worldwide Rick Dee's Weekly Top 40!
