I agree that WinMX is probably the best option for mp3-sharing at this point. I am able to find far more AND higher quality songs with it than *cough* Kazaa *cough*. And since the network administrator on our campus blocked the Kazaa port, I had no choice but to try it.

Anyone know if there is a file-sharing program that will actually list what program the mp3's were encoded with? (before downloading them, obviously.)
