How about LilyPond? It uses its own plaintext notation, but uses TeX for output. The engine itself uses a whole slew of measures to analyze the music and produce pretty sheet music, so it's automated to a much greater extent than MusixTex is.
It seems to me that what you really want, is to customize the look of the captions. This is most easily done using the caption package. For instructions how to use this package, see the manual (PDF). You would probably need to create your own custom caption format, as described in chapter 4 in the manual.
Edit: Tested with MikTex:
\documentclass{report}
\usepackage{color}
\usepackage{xcolor}
\usepackage{listings}
\usepackage{caption}
\DeclareCaptionFont{white}{\color{white}}
\DeclareCaptionFormat{listing}{\colorbox{gray}{\parbox{\textwidth}{#1#2#3}}}
\captionsetup[lstlisting]{format=listing,labelfont=white,textfont=white}
% This concludes the preamble
\begin{document}
\begin{lstlisting}[label=some-code,caption=Some Code]
public void here() {
goes().the().code()
}
\end{lstlisting}
\end{document}

This is a so-called italic correction. Its purpose is to ensure proper spacing after italic text.
Example:
{\itshape M}Mproduces MM, but italics M touches normal M.{\itshape M\/}Mproduces M M, with a bit more spacing to avoid touching.
