I'm not sure if you can even find this anymore, but Sonic Foundry Siren Jukebox is what I use. I know Sonic Foundry no longer offers or supports this, so this suggestion may be of no use, unless you message me and get the copy I have. It is (was) a free program and Sonic Foundry does still allow the online registration required to activate it. The only drawback to it is that the free version does not allow burning or ripping and the EQ is disabled, but there's much better progs for burning and ripping and the EQ doesn't really matter (at least to me). In Siren you can organize your files and make playlists (although the playlist feature is really slow to load). By default, when you scan your drive(s) for mp3s, it will automatically sort them by artist, album, genre, artist/album, & more. Of course, in order for this to work, you must have the files correctly tagged in ID3v2 format.
As for organizing your mp3s, I highly recommend Tag & Rename 2.05 (or higher if they have released a new version). There is a free version with no time restriction, but it only allows the auto-renaming of 10 files per folder. If there's more than that you have to do the rest one at a time. It's well worth whatever they are charging if you have a large media collection. Get more info

As for burning, Nero Nero Nero. I use 5.5.9.9 which has an awesome SVCD plugin for converting almost every video format to svcd.
Ripping, I use CDex. It's free, it does everything I need it to and it uses Lame encoding. It will also write ID3v1 and ID3v2 tags. Not sure if this is a common feature, but the last encoder I used did not support v2 tags and 95% of the music I download is not tagged in v2. Since Siren uses this, it is important to me.
