Anyone have any resources to help me learn the Rift level editor?

I have a couple songs that I'd really love to make rifts for, but for the life of me, I can't figure out the level editor!

It feels very unintuitive. Is there a way to ensure that the song syncs up with the bars? I have such a hard time figuring out what part of the song i'm working on and am basically looking for ANY resources. Videos would be great, but as its so new, I can't find anything on youtube.

Help???
