I've used WinMX since 1.2, but now people are just a$$holes on it, 4 out 5 of my downloads ended up saying "Connection lost; aborted by user", and these were not huge files mind you, I only download MP3s via P2P progs (IRC is reserved for the other stuff). So, I've tried AudioGalaxy, and I liked it, but it doesn't have enough of interesting material for me. I really like Morpheus, it reminds me of Napster in its usefullness for getting MP3s quickly and easily, but the current preview release has quite a few bugs, and some security issues which MusicCity or Kazaa should look into.
Glen, I hope you've properly uninstalled Webhancer, because that spyware is installed by AudioGalaxy without your authorization.
