Coldplay constantly watch audiences during gigs to refine song lists

Washington: English alternative rock band Coldplay constantly watch their audiences during concerts so that they can figure out which songs they are enjoying, and eventually refine their set list.If the ``Fix You`` hitmakers see people getting restless during certain songs, they axe the track from subsequent shows.

"In some songs all you can see is a clear doorway and you can hear the crowd singing so you think, ``Wonderful, this song is great.`` And then it`s when the light all starts getting blocked and everyone`s going to the bathroom. Then you`re like, ``OK, that song`s out,``" Contactmusic quoted frontman Chris Martin as saying. The quartet, presently regarded as one of the world`s biggest bands, started the UK leg of their world tour last weekend. ANI
