Coldplay - Viva La Vida Chords & Tabs

These are basically the same chords as all the others, but there's a problem. Everyone
doing C#, D#, G#, Fm, but the key is actually A flat (or Fm, but it's the same thing).
while the chords themselves are the same, it's important to be in the right key if 
going to sing the song or improvise. The main thing is it's in a flat key, not a sharp.

So, here are the correct chord names:

Vida la Vida

Key: A flat major (small chance it's the relative minor, Fm)
[ Tab from: https://www.guitartabs.cc/tabs/c/coldplay/viva_la_vida_crd_ver_3.html ]
Intro: Db  Eb Ab Fm x2

          Db         Eb
I used to rule the world
          Ab                    Fm
Seas would rise when I gave the word
           Db               Eb
Now in the morning I sweep alone
          Ab                Fm
Sweep the streets I used to own

Use the same progression for the rest of the song. If the chorus is different, I
My main point for posting this was to show that the song is actually flat.
