"Hang On" is a single from Plumb's third compilation album Beautiful History and is one of four original songs featured in the set. "Hang On" was recorded to be used in the 2009 original soundtrack to the film Twilight: New Moon but did not make the cut.[1] The track reached the top spot of the BillboardHot Dance Club Play in 2009 and was her first number-one single of 2010 on Billboard's Hot Dance Airplay chart.
In a profile and interview about the artist in Billboard, singer-songwriter Tiffany Lee Arbuckle notes that "Hang On" was written about finding hope when you feel hopeless, and dedicated it to her longtime fans.[2]
