Winamp Browser Plug-in
First of all, I want to say that I love WinAmp... I've tried many other media players but keep coming back to this simple but elegant program. The only thing that keeps it from being _perfect_, though, is ONE thing... an Internet Explorer plugin to call it up! I use MIDI files a lot, and Winamp is the only player to bring them up correctly, first time, every time. All other players screw around with the drum track quite a bit. If WinAmp had a plug-in to call it from Internet Explorer, it would blow Crescendo (and this Karaoke Player deal I tried today) right out of the water! A MIDI file plugin would make may day, as would a plugin that could stream MP3 or WAV (though that would be unneccesary if a MIDI plugin was written).
Anyway... my 2¢.
