Depends what mood I'm in and what period of my life I'm reflecting upon.
Some days when I think back on my WT rebellion songs like Firestarter by Prodigy are appropriate.
Other days if I'm feeling vulnerable and introspective I will grab a glass of wine and sing along at the top of my lungs to a few oldies but a goodies like I Want To Know What love Is by Foreigner .
There is no one song for me I love and can relate to so many.
