Marco,
Early on in my time here I used to loop my preview files for the same reasons that you stated you wanted to do it, however it is something that AJ no longer allows. I recall having to stop doing it a long time ago due to a posting from perhaps Scott (?). Either way, I’m certain someone else will confirm that this now a no-no.
An alternative solution is to loop the file yourself a few times and actually create a file for sale that is a minute long. That way the length of your preview matches the length of the file you are selling (and hey, a one-minute song will sell for more than a 20-second song, as well). 
Best of luck here at AudioJugle, Marco. It’s a wonderful community.

One more vote for you, Gareth. Your game looks pretty killer! Keep us posted on its progress, man.

I have no lag issues whatsoever. I’ve got to say that I love this game. I’ve lost about 30 hours that otherwise would have gone to music production to this game so far. 
In fact, I’ve had Ministry of Rock for three days now and haven’t taken the couple of hours to install it yet because of the fact that I’m not sure I can go that long without playing CoDBO at this point! lol
Very much appreciate you taking the time to post, Daniel. Thank-you! 
Way to go! It’s a great feeling, isn’t it? 
+1 here as well. Good idea! 
VERY exciting!!
runs off and works on DO-RE-ME’s
