While I don't share the hate that Coldplay and Jason Mraz inspire, I have to agree that the Matt Kearny tune is drab, even by AAA standards. Personally it's reaching the Kenny Wayne Shepard level of annoyingness.
I actually like the Matt Kearney song but I agree it's starting to get annoying. They don't need to play it that much, maybe once a day is ok.
Coldplay - I really tried to hate them. It wasn't hard at first because they kept on releasing extremely annoying songs (i.e. Yellow, In My Place) while the non-annoying ones (Trouble, Shiver) were rather forgettable. But these days they keep on coming out with very tolerable songs...I've found myself keeping on the radio during Speed of Sound, Life in Technicolor II, The Scientist, and the acoustic version of Lost. Clocks is good but I'm burned out on it.
Jason Mraz on the other hand - I was cool with him during "The Remedy" (which wasn't perfect, but likeable enough) & "You & I Both." Then he ruined me with "Curbside Prophet" ("what's up with M-R-A-Z?" Are you serious?) and hasn't redeemed himself since.
