Winamp is an untouchable for me. I must have been using it a good 8 years now and whilst I have tried several others over that course of time, nothing has come remotely close. Simple to use. Plays everything I've ever asked it to. Skin support is just fantastic. Can really make it look classy. Never had problems with it crashing or eating too much memory (though there are lighter options around). Has all the streaming, radio links, burning/ripping extras etc. What more could I ask for?
