Okay guys, I got a problem. I've decided to start writing music already. I'd like to do it all from "0% to song."
The thing is when I come to the actual writing: I prefer some nice guitar riffs with a Metallica/Bullet for my Valentine tone and good lyrics like Nirvana/U2.

As you may notice the instrumental part would never fit such lyrics, so I ask,
¿Has there been any band to play such polemic songs?
If the combination is always disastrous, ¿what would you recommend on lyrics theme to fit the metal-like sound?

You know, many metal bands are GREAT guitar players, but when it comes to singing they make me cry.
I agree with Martin, you can do whatever you want, it just might be slightly trickier.
Too lazy to come up with a clever or relevant sig.
