I uploaded my first song because I wanted to edit it and even though the concept is very user friendly it only uploaded less than 40 seconds of a 2 minute video. I sent a message to find out what to do, but at first glance, not great.... So then I tried without editing... yes it saves it so if I want to have a link for people to listen it to it, I can use that.

My recommendation is to try it right away, play with it and ask questions.
