《》（也称为“O（Fly On）”，或简称“Fly On”）是英国另类摇滚乐队Coldplay（酷玩乐团）的歌曲，收录在其第六张录音室专辑《Ghost Stories》中。
《O》绝对是Coldplay所有歌中最特别的一首，刚开始听的时候只是觉得钢琴很舒缓，而且特别诧异中间的一段空白，听得多了也就理解了歌词，是一种绝望，一种想要追赶心爱的人或是其他在乎的东西却追不到的无奈。

O (Fly On)歌词：
A flock of birds
Hovering above
Just a flock of birds
That's how you think of love
And I always
Look up to the sky
Pray before the dawn
'Cause they fly always
Sometimes they arrive
Sometimes they are gone
They fly on
A flock of birds
Hovering above
Into smoke I'm turned
And rise following them up
Still I always
Look up to the sky
Pray before the dawn
'Cause they fly away
One minute they arrive
Next you know they're gone
They fly on
Fly on
So fly on
Ride through
Maybe one day I'll fly next to you
They fly on
Ride through
Maybe one day I could fly with you
Fly on
Fly on
Fly on
