When I'm putting together the thread, I go through every album and look at each single to see how well they charted. Fantasia had songs that charted high on Urban/rnb charts but I focus on the main chart which is the Billboard Top 100. I think she had a song that reached the 20s and that's really good. But I only list songs in the top 10 usually.
With that being said, she's had no hits in the top 10 or even top 15. A top 10 Single is what I consider a hit.
