Hmm… cvs rhythmbox seems to be a little better, but still really slow when adding all of my music to the library. Part of that is to be expected since it's getting metadata for each of about 2000 files, but it really shouldn't be as slow as it is. And for some reason, I think that the slowdown might be the fault of gtk (and specifically, the treeview). Just adding all of the files to a simple model from python with sorting takes about 50 seconds as opposed to about 0.2 seconds without sorting. Yowzers.
