Happy 50th birthday, American Top 40! Ryan Seacrest is celebrating the iconic countdown show's 50th anniversary this weekend by kicking off AT40 Rewind where we'll relive some of music and the chart's most memorable moments, including when artists like Kesha heard themselves on the radio for the first time.
Over the decades, countless artists have had huge emotional reactions to hearing their song hit the charts for the first time and Kesha's own reaction will brighten your day.
The songstress recalled when she first heard her uncredited chorus on Flo Rida’s “Right Round” and also the moment she heard Seacrest mention her name and song “Tik Tok” hitting the charts.
This weekend marks just the kick-off of the 50th celebrations so stayed tuned every weekend to relive even more iconic moments with Seacrest!
