Agent Reno, With an Electro-Rod and his Wits!
While some say the guitar seems out of place and jarring, it isn't quite a classic piece, but another one of those Clancy-esque government conspiracy dramas. Yeah, it's like Broken Arrow, Enemy of the State, Paycheck, or Minority Report. The end clips off too soon, of course, meaning it can't be used in a game without further tweaking (like a fade-out), and then it's only useful in a movie.
It also reminds me of Turok II: Seeds of Evil, where Joshua Fireseed, aka Turok, first strolls through the Port of Adia; the piano got me there. Then again, the strings weren't as pronounced here as they were in the Port of Adia. Another soundtrack that comes to mind is Final Fantasy VII... the Bombing Mission. Rearrangements of that tune almost always include its relentless piano, its chief lure and source of tension.
Yeah, this can work for a flash. I still say you hold onto these and whip them out when a major for-profit animation team requests that you do... after you're in their ranks, of course. I do not like the idea of where my money will go if I don't pay you directly for the ability to use these tracks. See, the service that mediates your tracks would get a cut that's far too big for what those guys are really worth. Also, they might have some kind of fine print that removes all sense of ownership from you, thus you might be selling your soul if you take that route.
In any case, keep up the good work, and make sure you're justly compensated through the proper fashion.
