What was the last disco song?

It is difficult to pinpoint the exact "last" disco song, as the disco era gradually transitioned to the post-disco era in the late 1970s. However, some songs are considered to be among the last hits of the disco genre:

1. "Last Dance" by Donna Summer (1978)

2. "We Are Family" by Sister Sledge (1979)

3. "I Will Survive" by Gloria Gaynor (1978)

4. "Boogie Wonderland" by Earth, Wind & Fire (1979)

5. "Shake Your Groove Thing" by Peaches & Herb (1978)

These songs still carried the upbeat, dance-oriented style of disco, but also blended elements of other genres that emerged during the musical shifts of the late '70s. As disco transitioned into other styles like funk, soul, pop, and new wave, these songs marked a significant end of an era in music.
