Kevin, I pulled every song off both lists from a "top 100 disco songs" list. Granted, it WAS a Google search that got me the lists, but I sure think they all fit into the disco category.

Disco had more variety than the BeeGees and KC.

For better or worse, I think disco is coming back. I was at a jam session last night and we ended up playing "Boogie Oogie Oogie, "I Will Survive" and "Le Freak".
