So I've really wanted to make a mix for quite some time and am not looking to go out and buy the hardware to do it. I know some of you may just roll your eyes at this, but is there any software online that I could buy/download to be able to do this. Keep in mind I've never done this before and am beyond new to the idea. Not looking to do anything crazy just have a seamless mix so the most basic stuff will do. Figured this would be the best place to ask for help..

would really be appreciated all, thanks
