@oracle depends on what you want...

I guess @videolan / #VLC is too spartanic for your needs?

Maybe #Audacious or #AmaroK is more up your alley??

Or maybe #Phiola or #Dopamine???

#Qmmp looks very #WinAmp-esque to me...

Personally I'm just "#RawDogging" VLC in the background, but your use-case and mileage as well as necessary features may vary, so I can only recommend to look at @alternativeto and check the results...
