Winamp is free from Nulsoft. I use the earlier version that doesn't fade because it works better in a folder/window for track selection. With the earlier version - you have a list of songs in a folder, just like a text doc would look, and you simply hit enter and the song plays in a separate window(player).
You can drag songs into the window for successive play or scroll to a new song and hit enter again and again. The new software requires a second click of the mouse to activate the song window after one has been played. If a song is playing .... I can no longer scroll through the list until I click somewhere inside the window to "select" that window. That's cumbersome.

....as for fades - it's not that important to me or my clients. A 20-something crowd expects beat2beat mixes at dance clubs but at a party or wedding I mix up the program so much that a seamless fade is not neccisary. The files play instantly, and with any expertise at MC-ing, you can cover the tiny spaces between songs very well. Who ever said that there should never be a single second of silence at a party? I hate that constant drone of a "boom, boom, boom" song that seems to last for 20 minutes. I've outgrown that a long time ago.

Esh, I do occasionaly have a client that brings a CD in from the car, but if i don't know the artist AND the track ... I won't play it for fear of offensive language that would reflect on MY performance. All my modern tracs are radio edits and never is a colorful explitive heard at my parties.
