foobar2000, I've been pretty sold on it since I started using it. The weird thing is, I started skinning it and installing plugins and whatnot and got myself a pretty sweet setup, then when I got a new computer I just never bothered to move my setup over even though it'd be easy to do, and since then I've been using what is essentially the default setup and look with a few plugins I like, and I've never really looked back. It's not pretty, but it's so neutral-looking, so functional, intuitive, and easy to use just the way I want to use a music program, that it's basically become a sort of non-entity. It's like it's not an application, it's just music. I'm not starting foobar2000, I'm just putting on some Dylan. That's how I want everything on my computer to work.
