I'm submitting a song for SLS20 consideration. I'm submitting "Viva La Vida" by Coldplay.
Someone came up to me the other day and said the new Coldplay song was the best Coldplay song they had ever heard. I found this shocking. I like "Viva La Vida" as much as the next guy, but I didn't even feel compelled to nominate it for SLS consideration.
My brain quickly ran through the songlist of Parachutes. Surely "Don't Panic" is a better song. "Trouble" and "Yellow" are as good, if not better. And there are several song on A Rush of Blood to the Head that are in the same ballpark.
Then, I listened to "Viva La Vida" again. It's very good. It's no "Don't Panic", but it's most definitely worthy of SLS consideration.
