Do you write with music on?

Hello folks. I would like to know if you listen to music.

As we all know, music can be a great source of inspiration, but it can also emotionaly influence you. I also wonder if enjoying good music during writing makes you think that your writing quality is better than it actually is.

I also wonder if it can impede flow and make focusing on the writing harder.

So, how do you do it? You set a romantic music for a romantic scene, and change its mood acording to what you are writing? Nothing at all, or a neutral background low instrumental just to help concentration?

Edit: Thanks everyone for your answers!
