Rich, that looks like a nice piece of software, but it's a lot more than I need. I'd also have to buy an extra plug-in to support karaoke.
I know WinAmp isn't seen as a "professional hosting software system," and if I did club DJing & needed to beat mix, I agree that WinAmp wouldn't suit my needs. But for karaoke, I basically slam mix (my background is radio), I delete the silence from the beginning of all my non-karaoke mp3's and leave 4 secs silence at the end for fading into the next song. My shows always run smooth & a lot of fellow karaoke hosts in my market are impressed that I run my shows with (basically) freeware & a few inexpensive plugins.
I have tested a number of hosting suites (Tyrannosoft, ASPSoftware, MTU), and I found that they do all the same things I can do with WinAmp at 1/10th the cost.
