My Chemical Romance did "Danger Days" back in November of 2010 and you can read the wikipedia if you care about boring bio/fact bullshit. For me, music exists in a vacuum and it doesn't matter what the artists thought when they were making it; even idiots can make exceptional music. If it says something to you, it's great music. Context is vital in artistic appreciation, but I suppose it's the listener's prerogative as to how much context is enough.
