The music
Why? So you can justify to your mahspace friends that you're a hacker? Through a song?
If you're talking about music where the lyrical content is about hacking, I can't help you. However, there are some artists who use "hacking" techniques to produce sound.
Autechre is well known for composing songs made with programming languages like jMax, puredata, etc.

Aphex Twin is also very intelligent and "hacker-like" in the way the music is created.
Math-Metal bands oftentimes have a "hacker" mindset in their compositions, creating skittering time signatures and complex beats. look some of them up.
