Sad Songs

I personally love listening to all kinds of music, as long as its got some meaning to it. Sure, a lot of these songs end up being classified in the general "sad" category. But there are so many different types of "sad". People ask me sometimes why I always listen to "sad music". I don't. I listen to music with meaning. Now, it could be that there is a lack of non-sad music with meaning out there. But I don't necessarily like a song for its lyrics. Sure, the lyrics could be helpful at times, depending on how I'm feeling. A good example of this is Comfortable by John Mayer. It's got great instrumental to it. The violins are amazing. And the lyrics are in fact sad. The main thing I'm wondering is, does a sad person necessarily have to be listening to sad music? If somebody listens to sad music, are they sad? I know it's stupid, but I hate when people ask me why I listen to a specific song, because it's sad. Another example, Fix You by Coldplay, or Where Are You Now? by Honor Society. Every song seems to have at least two meanings to it; one from the singer and one from the person being sung to. What do you think?
