Even though I'm the age where most people the same age listen to rock/rap or other music, I listen to classical and celtic music.
When I'm feeling sad/depressed/angry/suicidal I listen to these pieces of composition.
I also listen to these pieces while I'm not sad or anything, but neutral/happy because they're some of my very favourite.
VAUGHN WILLIAMS (he is my topmost favourite composer all-time, and I listen to him the most. sometimes at night I just listen to him over and over and over again, during suicidal/sad/and-all-that-jazz moments.)
Fantasia on a Theme by Thomas Tallis
Fantasia on Greensleeves
The Lark Ascending
Five Variants of 'Dives and Lazarus'
and other pieces
Most of the Four Seasons compositions
PUTUMAYO PRESENTS: Women of the World --> CELTIC
most of the songs (eg, The Mighty One, and Against the Wind)
LOREENA MCKINNET (celtic/mixture singer)
The Book of Secrets CD
