In relation to my above comment, here's my thinking for each song:
A HEAD FULL OF DREAMS
Coldplay has done extremely well when they've opened the set with the first track on their new album. Square One and Mylo Xyloto/Hurts Like Heaven both served their places well.
DON'T PANIC/SHIVER ROTATION
Chris has said that they're enjoying playing older, not well known material. These are two gems from Parachutes that do not deserve to be ignored. The placement of this can show "hey, this is how far we've come since our beginnings."
A SKY FULL OF STARS
It's not like the band to completely ignore an album in a full show, but who knows. I don't expect anything more than ASFOS and Magic to be played from Ghost Stories unless somebody suggests otherwise during the request portion.
YELLOW
Do I need a description?
HYMN FOR THE WEEKEND
I do think they'll end up playing this song live, but from the performance I've seen on YouTube, they need to do some serious work. Unless they end up touring with Beyonce, her overdubbed vocal part is unnecessary and kind of creepy.
AMAZING DAY
After thrashers and fan favorites like Yellow and HFTW, Coldplay will need to take it down a bit. This and Everglow can serve that purpose while showing off some new material.
EVERGLOW
Read above.
CLOCKS
Slowly taking the crowd back up as they approach the end of the first portion of the show. This is a good combination between White Shadows hardness and Parachutes-esq softness that can ease the crowd back in.
LOVERS IN JAPAN
This probably isn't something that they're going to play, but it's among my favorites from VLV and is a good song that they could dig up from the vault. Also not too hard but not too mellow.
UP&UP
A great way to close out the set. You could also switch this one with Viva La Vida if you wanted to save another AHFOD song for the end of the show.
LOST!
Often ignored, I think this song would be a great "don't worry, we're still here" song. The upbeat beginning grabs and pulls you in. Also one of my favorites from VLV.
VIOLET HILL
One of Coldplay's best songs. Would be leaving the organized portion of the show on a ringing and strong note.
ADVENTURE OF A LIFETIME
They haven't touched AHFOD for a few songs, and this would be a good way to say "hey, don't forget about this." I don't see them playing anything else from AHFOD due to the fan pressure for older era songs. Thinking Birds or X Marks the Spot might work its way in later on or be featured often in the request portion.
EVERYTHING'S NOT LOST
I would have put Spies here, but my thinking is that song has a lot of meaning for people and will be featured prominently in the request portion. This is a nice song to let fans cool down after AOAL. Also an awesome song to grab from the vault.
TIL KINGDOM COME
Keeping things on a quieter note before the VLV songs kick back in. Hoping maybe they could pull back the Ring of Fire ending -- that worked well on the Twisted Logic Tour.
CEMETERIES OF LONDON/WHITE SHADOWS ROTATION
I'm actually considering removing Cemeteries, but we'll keep it here for now. If you're going to play a deep cut (a really deep cut), then White Shadows is the one to do. I remember hearing that song for the first time and my head just going off. I can almost say that it's their best song no questions asked.
IN MY PLACE
I agree with a previous comment that they could rotate this with GPASUYF, but I think the days of that song are over :(. Don't get me wrong, it's my favorite song from the first two albums, but nobody seems to want it anymore.
SPEED OF SOUND
I know this is a pipe dream since Chris apparently hates the song, but it's a good song that casual and die-hard fans will both enjoy.
FIX YOU
Awesome set closer! The ending of that song is sure to leave the crowd cheering for a long time. Could this possibly be rotated with Every Teardrop?
PARADISE
You can't completely ignore Mylo Xyloto but I just don't see the songs fitting in to this set that they're going after. This is just a good popular song that doesn't necessarily need to go with the feel of the rest of the album
MAGIC
Another pop number from Ghost Stories that probably won't be ignored. I find it forgettable, but whatever
VIVA LA VIDA
I don't think they've ever tried this song as a show closer, but I think it would do quite well. The crowd could be singing the ending "oh-oh-oh-oh-oh" refrain as the band walks of the stage.
I know this isn't perfect, but hey -- sadly Coldplay shows can't be 40 songs long. I'll be glad to take feedback/constructive criticism to my set and my post as I'm new to Coldplaying. And I'll even respond to it!! Enjoy
