The music you heard (and are hearing), if your web browser supports this, is "Nowhere Man" by the Beatles. Aside from my being a great Beatles fan, the reason for this music is the following pastiche of the original lyrics (author unknown to me). I've also included the original lyrics.

If you find this sort of musical background, or this particular piece, an annoyance, just click "stop".

    Unix Man (Nowhere Man)
    ======================

 He's a real UNIX Man
 Sitting in his UNIX LAN
 Making all his UNIX plans
 For nobody.
 Knows the blocksize from du(1)
 Cares not where /dev/null goes to
 Isn't he a bit like you
 And me?
 UNIX Man, please listen(2)
 My lpd(8) is missin'
 UNIX Man
 The wo-o-o-orld is at(1) your command.
 He's as wise as he can be
 Uses lex and yacc and C
 UNIX Man, can you help me At all?
 UNIX Man, don't worry
 Test with time(1), don't hurry
 UNIX Man
 The new kernel boots, just like you had planned.
 He's a real UNIX Man
 Sitting in his UNIX LAN
 Making all his UNIX  plans For nobody ...
 Making all his UNIX  plans For nobody.

Nowhere Man by the Beatles

He’s a real nowhere man,
Sitting in his nowhere land,
Making all his nowhere plans
For nobody.

Doesn’t kave a point of view,
Knows not where he’s going to,
Isn’t he a bit like you and me? 
Nowhere man, please listen,
You don’t know what you’re missing,
Nowhere man, the world is at your command.

He’s as blind as he can be,
Just sees what he wants to see,
Nowhere man can you see me at all? 
Doesn’t kave a point of view,
Knows not where he’s going to,
Isn’t he a bit like you and me? 
Nowhere man, don’t worry,
Take your time, don’t hurry,
Leave it all till somebody else
Lend you a hand.

He’s a real nowhere man,
Sitting in his nowhere land,
Making all his nowhere plans
For nobody.
