Johnny Cash: Hurt <- A strong reminder that when you sing your feelings out regardless of whether you have the voice or not, can be a great way to vent. Usually when I'm feeling depressed, I'll start writing down everything I feel and then bunch it all together to make music. I have a terrible singing voice, but that won't stop me nor should it stop you if you feel the same. I recommend it. Have a good one, sir/ma'am.
