The FACT is that there were several singles released by Fleetwood Mac that year, not just one. Here is the Wikipedia entry for their album The Dance:
"This album spawned three singles in the USA: "Landslide", "The Chain" and "Silver Springs", and earned the band three Grammy nominations in 1998, in the categories "Best Pop Album", "Best Rock Performance by a Group or Duo with Vocal" for "The Chain" and "Best Pop Performance by a Duo or Group with Vocals" for "Silver Springs". A fourth single, "Temporary One," was released in some European markets."
So we're both right!
But getting back to the topic of this thread, I don't consider the word "hit" to be a function strictly of Top 40 chart position. As I've said, there are songs that have become hits AFTER their initial chart run. That's what this thread is about.
