How do I upload my own mashup that I created in my head if it's telling me it's copyrighted. I understand Mashing up is just mixing 2 or more songs together but in your own image and what you think sounds good together. Others do it, so why can't I upload mine? I'm not trying to take credit for someone else songs but just expanding and showing a different light on it. If I'm not able to do this on my own accord what is the point. It's my own rendition of mashups that are made countless times a year. Thanks!
