Well for example I just streamed Viva la Vida from my ripped music library and nothing special happening bass-wise there. I even measured with a sound meter app to confirm.
What is your music source? What else are comparing to?
Don’t know why only Coldplay would have the issue. Are you a Coldplay fan? Maybe it’s just a special focus you have with Coldplay. Nothing special bass-wise with them in general I can detect.
Maybe a loudness wars thing perhaps if you are comparing most any newer pop recording to older releases say pre-1990s
