Coldplay

It is known to us that Chris Martin borrowed the name 'Coldplay' for his band from his friend.

But I wonder if he knew then the meaning of term Coldplay then. Well, even if he didn't know it, he kind of chose a perfect name to suit their band, say by serendipity.

Let's look into the meaning of Coldplay that we can consider in this context.

One meaning of cold is:

(usually with "have" or "know" transitively) PERFECTLY, exactly, completely; BY HEART.

And play: To produce music using a musical instrument.

This I think can be a plausible meaning, as this can mean, 'they play by heart'.
