I don't want to like Coldplay, and I don't really, most of their music is rubbish. But it's hard to deny the feelgood magnetism of 'Clocks'. Anyone who has a driving playlist will have that on there. What is that attractive, chiming instrument you hear at the beginning and repeated elsewhere? I reckon it's just a keyboard synth but it has a sort of xylophone/glockenspiel quality to it. I think if you replaced that sound with a blander one the whole song would be a lot less attractive. Conclusion; bands ought to use that electronic, chiming sound more often.
