Radio automation, anyone?

In my previous post, I mentioned about using Izotope Ozone - well, I've found an alternative. For some reason, Ozone seems to leech my CPU power (it's a hyperthreading-based CPU, not a duo-core). Sonitus:FX seems to do a MUCH better job - I'll post more in another post.

But what I'm looking for is - does anyone know of any good radio automation softwares? No, I don't work at a radio station, but I find it very surprising that stations use Winamp for on-air playback... and if that's the case, how do they crossfade etc? Running multiple instances of Winamp can hog your PC down, and unless you run playback on multiple PCs, I don't think it's that easy to have one PC dedicated for on-air broadcast.

I know there are a few useful plugins for Winamp for crossfading (such as SQR Crossfader) but they haven't really been updated in ages and are buggy with Winamp's latest version (at the time of writing this post). But a drawback of radio schedulers is that you can't use your DSPs for on-the-fly audio processing - something I really like about Winamp.

So - does anyone have an idea which radio automation software is
1) easy to use, and
2) available for demos? (I know of only one software - Zara Radio - that's free, but it's a little more complicated to use)
