what a feeling

It seems that "What a Feeling" is most commonly associated with the song "Flashdance... What a Feeling" from the 1983 film Flashdance. The song was written by Giorgio Moroder and performed by Irene Cara. The lyrics describe what it feels like when music inspires someone to dance, and the song was intended to act as a metaphor for achieving any dream a person has. However, without more context, it is difficult to determine what exactly is being referred to by "what a feeling."
