Song can save life by their words of savior, but what many understand is that this saying is for "suicidal emo freaks". No, most people who are the happiest listen to music when they feel sad. They don't know it but when  they understand the lyrics and get up and try again because they felt happier for some reason. This is because when they heard that song lyric and understood them,  but what they usually don't know is that the song saved them from the sad part.

It doesn't have to be music it could also be a quote from a famous scientist, director, skater, writer, artist, or a athlete. Some times other peoples words are another person life saver. In pierce the veil they "Without you there is no me". I see it as they are saying if you're gone in any way I would sad or I would miss you. I don't really no.
