Is there a free media player suitable for classical music?

I would dearly like a media player that's suitable for classical music
(95% of my listening material). Every new version of Windows Media
Player seems to be harder than the previous one to use effectively
with classical music, and now I'm on WMP 11 I'm finding it very
frustrating.

I have no problem with manually entering the track info for every
track; I'm used to this anyway. My issue is more along the lines of
organising my music. Principally, I'd like to be able to organise my
media library by composer as well as by album title. I'd like to be
able to do this for on-disk storage too. I'd like a media player that
doesn't insist that the performing artist is the most important thing
I need to know.

I don't necessarily want something that's explicitly geared towards
classical music (though if such exists, I'd be grateful for a link).
Something that's configurable enough for me to tell it how I want it
to deal with my music is all I want. Does anyone know of anything like
this?
