Someone Else's Song Lyrics

I can't tell you anything you don't already know.
I keep on trying, I should just let it go.
I keep on singing, you're eyes they just roll.
It sounds like someone else's song from along time ago.
You already know the story and the chords are just the same.

[ Lyrics from: http://www.lyricenter.com/e53835-wilco~someone_elses_song_lyrics.html ]
You already know I love you, and I sound like whats-his-name.
But you can't stop me, I want you to know.
I know it sounds like someone else's song from along time ago.
