This song was originally performed by The Smiths. The version on Charmed is done by Love Spit Love and could be found on the OST for The Craft.

I am the son
And the heir
Of a shyness that is criminally vulgar
I am the son and the heir
Of nothing in particular
You shut your mouth
How can you say
I go about things the wrong way
I am Human and I need to be loved
Just like everybody else does
There's a club, if you like to go
You could meet somebody who really loves you
So you go, and you stand on your own
And you leave on your own
And you go home, and you cry
And you want to die
When you say it's gonna happen "now"
Well, when exactly do you mean?
See I've already waited too long
And all my hope is gone
