It's simple! All you do is take one track/song from each release and put it onto the release that came before it. It could be one that you think fits best on that album, one that you think fits better on that album then the one it's on, or just one that you would have like to seen on that release instead... anything.

 

The only rule is that a track can only "skip back" one release so, for example, you couldn't put Strawberry Swing on A Rush of Blood to the Head.

 

Here's mine:

 

We Never Change from Parachutes goes onto The Blue Room EP

In My Place from A Rush of Blood to the Head goes onto Parachutes

Til Kingdom Come from X&Y goes onto A Rush of Blood to the Head

Lost! from Viva la Vida goes onto X&Y

Glass of Water from the Prospekt's March EP goes onto Viva la Vida

 

now yours...

Don't Panic from Parachutes goes onto The Blue Room EP

Warning Sign from AROBTTH goes onto Parachutes

Square One from X&Y goes onto AROBTTH

Violet Hill from VLVODAAHF goes onto X&Y

Poppy Fields from Prospekt's March EP goes onto VLODAAHF

Let's do this with the current releases, shall we??

Kaleidoscope from A Head Full Of Dreams goes into Ghost Stories

A Sky Full Of Stars from Ghost Stories goes into Mylo Xyloto

Us Against the World from Mylo Xyloto goes into Prospekt's March

Life in Technicolor ii from Prospekt's March goes into Viva la Vida or Death And All His Friends

Reign of Love from Viva la Vida or Death And All His Friends goes into X&Y

A Message from X&Y goes into A Rush of Blood to the Head

And, as a bonus...

Bigger Stronger from Safety EP is similar to Ode to Deoderant

Ode to Deoderant goes into... wait, there are no more Coldplay releases! :P

Let me revive yet another magnificent thread. Can't believe this died after just one freaking post. It's actually a pretty cool game to see everyone's opinion on how the songs sound... And also, there'd be new people joining all the time so there'd be no reason for this thread to die ! :D
