Wow I just need to say that even if you were deaf and couldn't hear a note of their music, their lyrics alone are exceptional. Throw in a charismatic frontman and you have two reasons right there for their success. As I've told my son (a musician), quite frequently it's not about the talent. It's about performance, charisma, street smarts, connecting.... and having something special that the possibly more talented artist just doesn't have. There are plenty of hugely talented musicians playing alone in their basements to an audience of one. Watch Twenty Feet From Stardom on Netflix and it will clarify it even better than I ever could.
Here's an example in my opinion, of brilliant lyrics:
About a breakup. Boots and Hearts. I mean who compares hearts coming apart to boots coming apart? But it works....it's a great image.
I feel I've stepped out of the wilderness
All squint-eyed and confused
But even babies raised by wolves
They know exactly when they've been used
See when it starts to fall apart
Man, it really falls apart
Like boots or hearts, oh when they start
They really fall apart
Ooo fingers and toes, fingers and toes
Forty things we share
Forty one if you include
The fact that we don't care
