I do the music thing. Listening to music as I write. Not so much music that matches the mood, but I start writing with a craving for a certain band or genre of music, and write to that. Usually I can go for chapters with just one cd. When I change to something else, it's often similar in sound. If it's very different, I don't listen for very long, just once or twice (which seems to shift the focus enough to jar my brain out of whatever rut it's in), then switch back to the original cd.
I can write the entire first draft of a novel with just a handful of cds.
Some people write in complete silence, others with music, others (I have a friend that does this) while playing movies in the background.
[I tried that with Pirates of the Caribbean, because SH has pirates, I thought it might help, but it didn't. Of course, the circumstances weren't ideal--my little sister was in the room and trying to talk to me as well. Very distracting.]
The point, to repeat what I say in a comment a few posts ago, and to echo WrittenWyrdd's words, is to write. And to get the book done.
Don't be afraid of doing it wrong. Especially not the first draft, don't get tied up in the 'right' or 'proper' way to do it. But if you're stuck, try something you haven't tried before. It might help.
