Wake Up Song of the Day: Rachel Platten “Fight Song“. It’s a “One Hit Wonder Monday” song! For our purposes, defined as a singer or group known for only one song to chart on the U.S. Billboard Top 40. Or, even if a second song is on the chart, it is overwhelmed and generally forgotten because of the success of the “One Hit Wonder”. In 2015, Rachel charted #6 with this song. Also in 2015, she charted #37 with “Stand by You”, but nobody remembers that song! Some argue whether she is a “One Hit Wonder” considering she’s young enough to still have a more successful career, even though her first album was released in 2003.
