"a mess*" = Inside the 10cc album The Very Best, are some tracks from Godley&Creme (former 10cc members), but because albumprinter (merely) is reading the tags it says I have an artist's folder named Godley&Creme. I don't, it is a 10cc album = a mess.
Come to think about it, you know there could many other examples like this.

At the risk of sounding defensive, I'd already mentioned in a previous post that VA (various artist) albums weren't handled (though they could be).  Also, I didn't want to depend on the directory structure since everybody is different when it comes to that.  For instance, I have a couple of root folders e.g.:

/Normal/P/Pearl Jam/[1991] Ten/01 - Once.wv
/Emulated/SNES/Seiken Densetsu 3/sd3-1-01.spc

The OP wanted to know the music format as well.  Anyway...no big deal.  The OP appears happy and that's what counts.  Thanks for your feedback. 

skwire, you are da man!!
I love this program.  Let me tell you my history with this issue:
Before the days of good desktop indexers (Google Desktop, Everything, X2, Copernic, etc.) it was very important for me to catalog the mp3 files on my computer.  I eventually settled on MP3 Collector, which was great at the time.  Since then, it has stopped being developed for the most part.  The BIG complaint with MP3 Collector was that it would export a list of the UNIQUE albums that you had.  It would give you just a list based on each mp3 file.  So if an album had 12 songs, there would be 12 lines in the list.  But all I wanted to know is which albums I have.  The developers always insisted the program wasn't meant for that because mp3 files are not physically grouped or whatever reason they gave.  They were basically saying they just didn't want to do it.  Then they said they MAY do it later.  Years later, nothing has happened.

The whole reason why i want this is because when I walk into a record store, I want to know which albums I have and which ones I don't, so I don't waste my time buying something I already have.  So this program is EXACTLY what I've been looking for.

Great to hear.  Thanks for the feedback.

I'm thinking about the various artists issue.  I'm going to run into that also.  But it depends on how people tag these files.  I would think that most people have the "album" tag the same for an album with various artists.  Now, how do you deal with all the different names under "artist"?  Well, one thing the program can do is if it detects multiple artists for the same album name, it can assume that all of those are together, and either say <various> in the artist cell, or actually list all the different names (but that might be long and ugly looking).

Well, that's where the so-called "ALBUM ARTIST" tag comes in.

The problem with that is the situation where two different artists name an album the same thing.  Especially with stuff like "Greatest hits".  So, in a case like that, maybe the program can THEN check to see if the files are in the same folder.  But then what if you have the folders split into 'Disc 1" "Disc 2"...so the folders will be different, but it's really the same album?  ugh...this can get complicated.  but not impossible!  i can do this...give me time.

Agreed, there are a bunch of different scenarios that could occur so, at best, anything you do will be imperfect.  However, to give you peace of mind, Album Printer does handle "different artist with the same album name" issue.  It combines the artist name with the album name and uses that to compare against its list.  So, in other words, "Artist_A - Greatest Hits" is considered different from "Artist B - Greatest Hits."

So what happens when there's like a tribute album with several artists, and each artist is named as the "artist" on their track?  How does AP know the difference between that and a bunch of different "greatest hits" albums?

It doesn't.  That's what I meant in an earlier post when I said that various artist albums aren't currently handled.  There are a few methods that could attempt to handle this but the original poster didn't request it so I never added it.

OK, I see.  If I think of a good way to do that, I'll post it.

The perfect way would be for everything to have a proper ALBUM ARTIST tag but the chances of that are slim.  Another way is to check if a given album folder has only one artist.  However, this assumes the user has a properly formatted folder structure.  Not nearly all do; I know plenty of folks that still just dump all their music files into one folder.

I didn't mean using folder or file names.  I meant it more like if a group of files within a folder (most folks keep one album in one given folder) contained more than one artist, that "album" could be considered a various artists album.  Does that make things more clear?

Original poster would be me. I didn't ask you to translate AP into Amharic either, but honestly, don't some things go without saying?

I still marvel that a few hours after inquiring about software like this I had my very own program in hand. Thanks again. I only wish I had similarly catalogued all my LPs before they were stolen a few years back. I can't remember half the music I had.

superboyac, if you ever solve the classical music issue to your satisfaction please let me know.

Damn. I sincerely and humbly apologize, skwire. This was my obviously lame and misguided attempt at humor. Once again I have learned that things don't always come across in writing as intended. (I guess smileys do have a purpose after all.) I did not ask for and never expected an allowance for various artists and in fact declined your generous offers for additional features. I was merely trying to say once again that you quickly and expertly helped me out with your amazing skills. Please forgive my unartful comment. You deserved better.
