we could get an official viva la vida prospekt's march playlist from Coldplay themselves.

What do you mean? :thinking:

I want the band Coldplay to tell me how the Prospekt's March songs fit into VLV

If they were supposed to fit, they would've been on the album. If you asked Chris in an interviewer he'd say something about leaving it up to your own interpretation.

That would be exactly what chris would say. He is just that sort of person: not definite.
