Alright... I heard this song on the purevolume... I know that it is not
"Relient K" but rather "Matthew Thiessen and the Earthquakes" but... Matt T is
the lead singer of Relient K, so I consider this song to be Relient K.
I've tried finding some kind of chord or tab online,
but it was hard even to find the lyrics. I bought the mono vs stereo vol 2 and
I figured out the basic chords. i realize this is a piano song... so you will 
have to figure the piano out by yourself... at least the chords will help.
have fun.

Its in the key of G

Verse 1:
G D/F# Em Em-D/F#
G D/F# Em Em-D/F#
Am Em-D/F#
Am Em-D/F#

Chorus: (drums come in)
B---15-15-13-13-12-12-10-8   -or-   e---10-10-8-8-7-7-5-3
C G C G
(singing starts)
C G C G
C G C G F C-D/F#

Verse 2:
G D/F# Em Em-D/F#
Am Em-D/F#
Am Em-D/F#

Then it goes up to the key of Bb (or capo 3 G Em D/F#)
G---3-3-3-3-3-3-5-7-8---7---0---8-7---3

Bb Bb Bb Bb Gm F/A
Bb Bb Bb Bb Gm Gm-F/A  G (back to key of G)

Outro: (Quiets)
G G C C G G C C

end on G

Feel free to comment and correct.
I hope to see an in-depth piano tab or powertab sometime soon :)
