As for me, I sing without shame in the privacy of my shower or in the confines of my car (always alone) and I am always woefully off-key.
I dated a young man whose dream was to become a famous singer and entertainer and at 14 (me) and 15 (him) he would play his guitar and sing to me. We belonged to the local community center and there was a teen cafe where he often headlined the evening's entertainment - one night he dedicated a song to me, in front of everyone, and it was one of the most romantic things to ever happen to me. The song "Wild Thing" has never sounded the same ever again.
Since then there have been other songs sung to me or dedicated on the local radio station - Do You Love Me, The Worst That Could Happen, Lady in Red, Close to You, Through the Years, Have I Told You Lately... The day I was married our first dance was to We've Only Just Begun. Each time I hear one of these songs, or a few others I equate with significant events of my life, I feel flooded with nostalgia, happiness and a little bit of a return to my yesterdays.
When I wrote His Lucky Charm (originally titled Forgotten) I played Kenny Chesney's Because of Your Love on a continuous loop; for Courage of the Heart it was Once in a Lifetime by Keith Urban; currently I'm playing Kenny Chesney's (again) I Lost It for my present WIP (a sequel to Karma Visited). Music seems to reach right down, grabbing my emotions and shaking them up so that I can pour words onto paper and hopefully connect with my readers' emotional intellect.
What about you? Are there any songs which have special meaning?
