1000 No. 1s: Watch Tiffany Chat About Topping The Hot 100
1000 No. 1s Video Series Day 13:
Tiffany Talks About Topping the Hot 100
2011 was the year that Billboard celebrated the 1000th No. 1 song on the Hot 100. As we look back on this year in music, we're celebrating that milestone with a month-long series of videos --- one for each day of December -- chatting with 31 of the hitmakers who rocketed to the top of the chart since its inception in 1958. SEE THE FULL CHART HERE.
The '80s teen sensation didn't realize the impact of her "Could've Been" either -- which peaked at No. 1 on Feb. 6, 1988 -- till she saw it on her fans' faces. "I think it took a while for me to really understand [that] people like me [and] people like the song," Tiffany said. "That didn't really start to effect me until I started traveling and seeing people's faces and how they reacted to me."
Be sure to come back tomorrow (Dec. 14) for the next 1000 No. 1s video: Nickelback talk about their No. 1, "How You Remind Me."
