I was trying to organize them by the composers (Bach, Beethoven and etc). This seems fine at first but then you have "special" edition pieces performed/conducted by renowned people (yo yo ma, gould, karajan, ashkanezy and etc).
It depends on how you're planning on listening.
I shoehorn things into the Artist/Album format so that my files make sense on my ipod as well as in Amarok, but I imagine it should be clear enough to see how it'd apply when you "properly" use tags.
Unless the performer is performing a recital (or something similar), I stick with the composer. For example, I have Itzhak Perlman doing Paganini's 24 Caprices. For me, it's:
Artist: Paganini, Niccolò
Album: 24 Caprices [Perlman]
I can search for Perlman if I want to, but it's organized as a Paganini piece. On the other hand, Horowitz in Moscow is a recital, and so the pieces are various movements from disparate works. Thus:
Artist: Horowitz, Vladimir
Album: Horowitz in Moscow
Generally if I have a full work, or excerpts from a work (As an example, I have a disc with three of the Six Moments Musicaux of Schubert; I keep this as Schubert because the disc is not an exposition of Jandó; I suppose it's a matter of judgment, to some degree), I organize by composer; only if a disc is clearly recital-like is it organized by performer.
This works for me because the composer is more important to me. I certainly have pieces where I prefer one performance to another, but that is secondary to the piece itself. But if you are a big fan of Yo-Yo Ma, for example, it would make sense to make him your top-level rather than Dvořák, Brahms, or whoever he happens to be playing on a particular disc.
