My favourite music player still has to be Sonique.
http://teliadk.tucows.com/files4/sonique196.exeUnfortuantely its no longer in developemnt but it could handle almost every music format including MP3, MP2, Ogg Vorbis, WAV, MOD, XM, IT, S3M, WMA, WMV
It had a cool stylized aesthetic design with a fluid, windowless interface and fully animated menu systems.
Its freeform skins were its coolest feature and it had some of the funkiest skins going.
