Is there a way to do professional crossfading in iTunes/Internet Radio Thoughts

Hi everyone,
If there is not a way to do this within iTunes, is there an app that will do it that is accessible besides RadioLogik? I know at least one person on applevis that uses RadioLogik, and while I love it, there are certain things that I want from Station Playlist, such as the random/shuffle button. If I don't know what to play at a certain time, I can hit that button.
Also, I'd like to be able to broadcast with Apple Music stuff, only possible within iTunes right now. NiceCast is a bit odd with having to go between multiple windows to do voice brekas.
Basically, I haven't found the ultimate internet broadcasting solution for the Mac. RadioLogik makes me plan my show from beginning to end and since this would be an internet broadcast I'd be doing that doesn't require that level of professionalism, I really don't want to do that. Maybe some of it, perhaps, but not the entire thing. I like having surprises in my shows--well, I haven't done one yet because of this issue.
Plus, RadioLogik still uses iTunes, despite sighted users not having to touch iTunes. I guess the blind users who use it are willing to do that, but I'd love to play music on my external drive, and a lot of that isn't in my iTunes library.
I heard someone was working with the MegaSeg developers, but I guess that fell through.
