Happy, sad, relaxed or mad, and everything in between, it is said that there is a song for every possible mood that one can feel. I am a firm believer of this and have started a soundtrack of my own. With my collection being a couple thousand songs strong it can be quite a pain to find the right song, at the right time. But on the other hand keeping the original library intact is also important. It's when the files are on my mp3 player, that it's divided into moods or however you'd like to do it. After all it is YOUR soundtrack.
My range of music has everything from the heaviest of Metal all the way to the soft sound of the story telling Folk/Roots music (there is a ton of others in between but i will focus on my go to music). Although Metal is depicted as being brutal and angry(which it definitely can be), it can also be beautiful. If you disagree your listening to the wrong bands. On top of that it can be stress relieving. Sometimes you need someone else to say the words you find/say. Folk music can help gain insight that comes with stories and experiences of the artist. So crack a beer and crank it up, because music helps to cleanse the soul!
