Dream On - Aerosmith
Reflects everyone, not just me. About aging, gaining wisdom, losing time, etc. Made me really think.
Over the Hills and Far Away - Led Zeppelin
Every once and a while a person feels philosophical, like I do right now. At the moment, this song is a great reflection. As you gain knowledge/wisdom, you become aware of your own ignorance. Just the fact you made it there is a great and relaxing thought. Some say ignorance is bliss, but it doesn't come close to the feeling of relief when you realize you are ignorant.
