Rock and disco: They’re two genres that are sworn enemies. But during disco’s heyday, it managed to sneak its way into songs by some of the biggest rock acts ever.

One of the best examples is KISS, whose 1979 studio album Dynasty is known for being heavily influenced by disco. The biggest hit off the album is “I Was Made For Lovin’ You.” Despite being a hit on the Billboard Hot 100, it’s a track that continues to divide some fans and even members of the band.

In fact, Gene Simmons said in a new interview that he absolutely hates one part of the song. That part? All the high register “Do, do, do” backing vocals.

“I hate it to this day, ” said everyone’s favorite blood-spitting Demon. “Except, stadium-fulls of people … they jump around like biblical locusts … ‘Do, do, do’ … and so I play along.”

In honor of Simmons’ love-hate relationship with the song, here’s a brief look at five classic rock disco tracks we all love. Admit it; it’s hard to deny these earworms.
