Mine would probably be "Boulevard Of Broken Dreams" by Green Day.
It just, really describes me.

If there's one theme song that describes me and my fears about why I'll possibly never find true love or a real friend...

It's Creep by Scala & Kolacny Brothers. :(

I'd post a link to the song, but since it's a cover version of the song by Radiohead, there'll be swearing in it.

Hm.. I'd have to say 'Life' by E-Type, for various reasons. For one, it's my favourite song, and has been since 2006 or so :B And for another thing, it kind of reminds me of my best friend, who doesn't have an account here, and the wacky internet adventures we've gotten into over the years XD Here are the lyrics:

I've got life

One more time
I leave behind these burning bridges
It's a crime

I am here
There must be somewhere I can breathe
Now take me there

It's time to see
I wanna make you breathe
Life can be whatever what you want it to be
You need the key
I'm gonna make you see
No more make believe, you just go~

I've got life
You're always on my mind
You gotta believe in something, alright
Forever by your side
I've got life
Just give me time to find
Whatever it is, it will be alright
Forever by your side
I've got life

I've got life

What's that sound
My destiny is bound for changes
Lost and found
You tell me
There's gonna be a showdown somewhere
It's irit

It's time to see
I'm gonna make you see
No more make believe, you just go

I've got life
You're always on my mind
You gotta believe in something, alright
Forever by your side
I've got life
Just give me time to find
Whatever it is it will be alright
Forever by your side
I've got life

I've got life

I've got life
Alright
You gotta believe in something, alright
I'm by your side..

We're gonna live forever
Don't let this be whatever
I'm gonna make you believe in something, cause
We're gonna live forever
If you never say never
We're gonna make it alright

I've got life
You're always on my mind
You gotta believe in something alright
Forever by your side
I've got life
Just give me time to find
Whatever it is, it will be alright
Forever by your side..
I've got life
