Trapt - Whos Going Home With You Tonight Chords

The key of the song is in Db Major (or C# Major?). The Gb9 chord can be replaced with 
Gb, but I don't think it sounds "full."  Keep in mind that I figured out this song in 5 
xD

(The song starts off with the chord progression found in the Chorus)

Verse Part 1:
Gb9
Don't think we ever really got it right
Db
Both you and I have always kept it bottled up inside
Gb9
Can you show me what it feels like to give yourself away
Db
Why can't I hold onto you [Why can't I hold on to you...]

Verse Part 2:
Gb9
There's no one around who picks me up when I'm down like you
Db
Do...
Gb9
And when you can't hear a sound will the silence drown you
Db
Too...

Chorus I:
Gb          Bbm           Ab
Who's going home with you tonight? Was it real or am I
Gb           Bbm         Ab
Part of your collection? Have you crossed the line?
Gb          Bbm           Ab
Who's going home with you tonight? Oh I feel like you're an
Ebm       Gb         Db
Open invitation. Is this how we say goodbye?

Verse Part 1:
Keeping secrets somewhere down below
I wish you had the heart to tell me that you sold your soul
So many things you couldn't let me know
You had to run away
Why can't I hold onto you

Verse Part 2:
There's no one around who picks me up when I'm down like you do...
and when you can't hear a sound will the silence drown you too...

Chorus II: (Same chords and progression until...)
Who's going home with you tonight?
Was it real or am I part of your collection?
Have you crossed the line?
Who's going home with you tonight?
Oh I feel like you're an open invitation
Is this how we say goodbye...
Gb         Bbm            Ab
Who's going home with you tonight? [Good-bye] x2
Gb          Db                           Ab
Can you tell me what is wrong and what is right?
Ebm        Gb             Db
Who's going home with you tonight...

Bridge:
Gb, Db x2

Gb
...It's getting harder to sit here alone
Db
...And I've been waiting I've been waiting and you still ain't home
Gb
...I have never ever felt so low
Db
...And I've been thinking I've been thinking Oh where did you go

Repeat Chorus II
