Although it's not exactly file organization, the biggest tagging headache for me has definetly been genres. I now use discogs genres & styles and any album in that database follows that system, but sometimes I get an album which is not entered into discogs and then I have to try and figure it out myself of course.

To organize one's music files by genre seems like a particularly bad idea to me, at least if you want consistency.

Organize it by Folders of genres, and subgenres inside of them

I use foobar, but I'm not into script writing so I use it basically with plugins and only basic customisation.

Also, I only put Disc Number in the Album title so that the folders are organised correctly both in and out of Foobar. Its not, strictly speaking, the wrong info in my eyes, just because I can't count the number of multiple disc albums I have where the gracenote or FreeDB tags have put that exact same piece of info in the same place!

I just use iTunes and leave organisation to the software. The only time I find it sucks is in relation to compilations but I tend not to go for them anyway.

I disagree as I just feel the name of Pink Floyd's The Wall f.ex is "The Wall" and not "The Wall Disc 1". That's not what it says on the cover. In my opinion, regardless of which disc you are listening to, you are still listening to the album titled "The Wall". In foobar, Disc number and Total Discs have dedicated metainfo tags where that info is supposed to go. If a database stores that sort of info in the album title, that's pretty awful I think and very unprofessional as it's clearly information that could (should) have its own place. It could also be that it is your tagger which appends that info to the album title.

On discogs (which I often use), Album Title and Disc Number are separate bits of info and my tagger puts the info in separate tags.

Luckily, as a foobar user, you can easily remap those parts of your albums titles to the disc number tags should you want to in the future. Oh, and you should get into the scripting part. It's really quite easy!

edit :

Some time ago, I started using two separate date tags. I consider date to be the original release date for the album, when it was first released. Then I also use a custom tag called Release Year which is intended for later releases of that album, f.ex remasters. So, a 40th anniversary edition of an album may have 1971 as it's date and 2011 as it's release year.

For folders, I currently keep the info like this :

1971 - In the Land of Grey and Pink [Studio Album, 2011 Rerelease]

I cannot stand it when my itunes separates discs.

In Musicnizer I found the solution of this problem in the special tab that allows you to create additional "Disc" entry for an album and add tracks from the second CD there.
