to be fair, a loop should be a lot shorter than 2 minutes, think 20/30 minutes. Loops are generally made for games and such, where filesize means a lot. A single sound file of 2,3MB would make up one quarter of a big game.
I like it, but you should make it shorter, or don't call it a loop.
I'll stick to half a minute or so (for loops), and if it runs longer, I'll just make it a full song.
Thanks for the advice.
