I am looking for a song, but all I know is one line from it.  It is
"Music is my business, business is good."

Hello!
I'm not a 'researcher' but here's my answer in hopes someone will make
me one! :)
Thanks for the answer, Alejandro, but i have some more to add.

After some searching (30 seconds) i found the Megadeath song, but for
$20 i figured it'd be worth more and also found:

"Blues Is My Business (And Business Is Good)"
See it at Barnes and nobles here:

Lyrics at: http://www.larrymccray.com/lyrics04.htm

And also 'Rockin is my business' by The Four Horsemen - Lyrics at
http://webhome.idirect.com/~muskokajoe/lyric/rocknsmybus.html

Another is 'Boogie is my business' by Michael Katon  - Lyrics at:

Are any of these the songs you were looking for? Please read the
lyrics and see if they ring a bell.

Thanks!

Here's a clip from the song, see if it's the one you're looking for:

Hello again!

secret901: Nice idea with the Clip!
For the Blues song theres a linked clip at:
http://www.content.loudeye.com/scripts/hurlPNM.exe?/~ttt-600005/0410790_0101_00_0002.ra

For the Boogie song, The artist dosn't provide a clip on his site
(although he proveds clips for others) so i'll assume he dosn't want
one distributed.

As for the Killin one, i was unable to find one, and i don't think it
would be 'right' (legally or in googles intrest) of me finding a
mp3/posting a section of one. Correct me if i'm wrong!

Thanks again,
-Matt

Umm.. Alejandro,  FYI..  I, too used the term "Music is my business
and business is good" on Google, and received results (some were
already given), but you can't ever say that something DOESN'T EXIST as
a researcher.

PS - JDKern, I'm sorry your question wasn't answered more thorougly...
I've been trying to find references other than what these guys have
been able to, and I haven't yet.. but I will still keep looking for
you.
