ROFL at IC25 not liking Third Eye Blind. I figured they'd be right up your alley.
And now for IC25's wrath: I liked Third Eye Blind's first album. Everything they did after was total utter shit, but "Semi Charmed Life" is catchy as fuck, and "Graduate" is a fantastic song.
That said, Coldplay is NOT overrated. Coldplay is easily one of the best bands to come out of Britain since Oasis. Every album is a killer, and they're so talented it's ridiculious. Some people don't like them because they're "whiney". Well so is Oasis. So is 99.9% of all British indie rock. Please, songs like "Talk", "Don't Panic", "Fix You", "The Scientist", are all classics. "The Scientist" and "Fix You" are two of the saddest and most beautiful songs I've ever heard.
Granted, "Clocks" got played out to death, but check out their album tracks. They're fucking brilliant, and if you're a fan of bands like Radiohead or Oasis, I don't see how you can criticize Coldplay.
Coldplay takes this easily.
