Flexstyle,
Thanks for the FAQ link, I'll read it tonight!
TheCharningRhino,
I hope it is not only about luck
In the past I did the same thing, but I just deleted all my music that has any material out of my own, so I will upload only my original sounds/melodies/music etc until I'm not 100% sure that it's OK to do that.
I never did (intentionally) any illegal thing in my life, and I don't want to, but if I don't know the rules, they are still apply to me.
I've bought all my VSTs and DAW, I want to be clear and clean about this remix "business" too before I do anything. I could calm down, if I knew I am OK with all the rules and law and similar annoying mindtwisting things like that.
