Oh come on Boulevard of Broken Dreams is awesome!
I personally have a strong belief that no song is actually BAD.
All songs have their own kind of talent. They all are good in some way.
Now, I think what you all may be talking about is the kind of songs you personally dislike.
However, the way most people are putting it makes it look like the song is bad and everybody else either sees or cannot see that.
So, let us simply have our own tastes. That's what brought us together, the common taste for one of the most spectacular and unique bands ever: The Beatles.
So, each song is good. We may simply dislike it.
Now, carrying on with the topic,
I personally believe Smells Like Teen Spirit is so overrated it makes me sick.
