Another complaint is that the iPod sync plugin often doesn’t quite work correctly. I actually duplicated my playlists on an old version of iTunes to sidestep the issue. Rockbox on my iPod caused songs to skip, so that was a non starter. A modded iPod is the perfect compliment to Foobar.
But anyway, get Foobar2000 it’s great overall :)

You could try DeaDBeeF. It's Linux first but there are Mac OS builds. I've tried it, may be a little buggy on Macs but could be worth a check to see if it works for you.
I also want albums to be sorted by (original) release year but don't want to put the year in the folder or file names. Similarly, I want to be able to search, and with classical music it is nice to be able to show by composer or conductor or soloist, etc. Tagging and a robust music library make these things easy. Using the file system does not.
Managing levels is very important if you're listening on headphones. Otherwise some songs that are too loud will really hurt the ears.
