You can also download lots of new plug-ins from the Sonique web site. They post new ones all the time, so there's plenty to do if you get bored with your MP3 player. Sonique also has great skin support. Unlike Winamp, in which the skins must be shaped like the original window, Sonique skins can be any shape or size. This really gives people a chance to get creative with skins.

With it's snazzy graphics, great feature set and rock solid reliability, you could expect Sonique to be fairly expensive.
