I still haven't found a solution better than winamp with advanced crossfading output (which was last updated in 2002) to DJ a party... I usually bust out my 5-year old PC because nothing beats the crossfader of winamp (coupled with the awesome keyboard shortcuts - the ability to search for anything in the ID3 tags and enqueue the song via keyboard is so useful for a DJ)

Anyone have a better solution?

Amazing reading here how many people still use the old versions of winamp... It's pretty much the only thing I use my PC's for.
