One morning I went to my 8am physical science lecture and we had a substitute. As I walked in, a very familiar song was playing over the sound system of the auditorium-like classroom. The lecture that day was on sound waves and properties of light so our sub thought it would be appropriate to play Coldplay's "The Speed of Sound" before class started. Being a die-hard Coldplay fan, I had heard the song before. However, when I heard it that morning it was like I was listening to it for the first time. I don't know if it was lyrics, the music, the imagery, or the fact that I was simply tired of being depressed, but I walked out of that lecture determined to be happier. I also realized that familiar songs sound so much better on good sound systems. This song became one of my most-listened-to, and I am not sick of it yet. My roommates (the good sports that they are) even allowed me to write phrases from it on our mirror.

Speed of Sound
Coldplay
How long before I get in?
Before it starts, before I begin?
How long before you decide?
Before I know what it feels like?
Where To, where do I go?
If you never try, then you'll never know.
How long do I have to climb,
Up on the side of this mountain of mine? 
Look up, I look up at night,Planets are moving at the speed of light.
Climb up, up in the trees,
every chance that you get,is a chance you seize.
How long am I gonna stand,
Look up, I look up at night,Planets are moving at the speed of light.
Climb up, up in the trees,
every chance that you get,is a chance you seize.
How long am I gonna stand,
with my head stuck under the sand?
I'll start before I can stop,before I see things the right way up.
All that noise, and all that sound,
All those places I got found.
And birds go flying at the speed of sound,
to show you how it all began.
Birds came flying from the underground,
if you could see it then you'd understand?
Ideas that you'll never find,
All the inventors could never design.
The buildings that you put up,
Japan and China all lit up.
The sign that I couldn't read,
or a light that I couldn't see,
some things you have to believe,
but others are puzzles, puzzling me.
All that noise, and all that sound,
All those places I got found.
And birds go flying at the speed of sound,
to show you how it all began.
Birds came flying from the underground,
if you could see it then you'd understand,
ah when you see it then you'll understand?
All those signs,
I knew what they meant.
Some things you can invent.
Some get made, and some get sent,
Birds go flying at the speed of sound,
to show you how it all began.
Birds came flying from the underground,
if you could see it then you'd understand,
ah, when you see it then you'll understand?
I'll start before I can stop,before I see things the right way up.
All that noise, and all that sound,
All those places I got found.
And birds go flying at the speed of sound,
to show you how it all began.
Birds came flying from the underground,
if you could see it then you'd understand?
Ideas that you'll never find,
All the inventors could never design.
The buildings that you put up,
Japan and China all lit up.
The sign that I couldn't read,
or a light that I couldn't see,
some things you have to believe,
but others are puzzles, puzzling me.
All that noise, and all that sound,
All those places I got found.
And birds go flying at the speed of sound,
