My suspicions were raised seeing a site using the Winamp name. When it didn't display anything but the background for a few seconds on my overpowered desktop and internet connection, I was afraid it was trying to run an exploit of some sort. I closed the page before even seeing it.

And while it seems that's not the case, I'm still suspicious of the project since it sounds like it's just going to be the same as any other modern music player, just riding on the Winamp nostalgia.
