There are only a few disco pieces that get rotation into my playlist, but they're among my favorite bits to listen to, including Donna Summer's "Hot Stuff", KC & the Sunshine Bands' "Boogie Shoes", Lipps, Inc.'s "Funkytown", Gloria Gaynor's "I Will Survive" (much prefer it with the Aborigine chant from "Priscilla, Queen of the Desert"), and a few others.
I don't hate or avoid any genre. There's something truly special in all of them, while 99% of the bulk of any genre is genuine uninspired crap. I sift through thousands of pieces in a genre and end up with only 10-12 that get into a permanent playlist. Out of about 200,000 pieces I have, maybe 1,000 get into regular rotation. Disco's no different.
