The early disco music had a dance beat but it basically sucked. There used to be LOTS of people screaming, "DISCO SUCKS", back then. Along came the BeeGees (with "Saturday Night Live") and some of that "hate" changed. Donna Summer was the catalyst for me (to start liking the music).

My brother and SIL were into dancing and they loved disco. My ex and I used to hang out with my brother and SIL a lot then and my main memory of the period was hearing, "Fly Robin Fly.... up up to the sky". I still get sick hearing that.
