Expression assistance - Same Album Name with 2 tracks #1
« on: November 14, 2013, 02:00:51 pm »

I need to find all Albums that have the same name and Artist which contain 2 or more #1 tracks.

I tried .. I really did.

You can use Search to do this:

   [track #]=[1] ~dup[artist],[album],[track #]

Maybe you'll also want to include [disc #] as part of the ~dup modifier.

You're welcome.  Also, you may need/want Album Artist (auto) instead of Artist.

One more maybe???

Since some of my albums have the same name (I have the view sorting worked out) I would like to have an expression to count the number of albums per artist. The albums with the same name are differentiated by

Series (if part of a box series)
Desrciption (5.1, HDtracks)

I would like to display the album count for the artist in theaterview under the artist's name. I did this before when I had unique album names, but I cannot figure how to do this now.

I have tried a variable on "Track #1" and add to it, and tried many ways with my sort expression but I have failed.

This is a different problem entirely.

So you want to count the number of albums per artist, and those albums are uniquely defined as [Album] + [Series] + [Description] ?

Yes totally different I know.. Your first solution worked wonderfully after a bit of panes tweaking.
I was looking for mismatched coverart....But thread was still short.

All Albums do not have all tags entered. Some [Series] have a description of Album Name if the series is composed of studio albums, like the Sector series by Rush.

I have under a single [Artist] for example Eagles & Rush


Artist                       Album Name                 Series                        Description              Disc #
Eagles
                              Hotel California         [Studio Albums]                                               4
                              Hotel California                                                   5.1
                              Hotel California
                              The Long Run
                              Desperado              [Studio Albums]                                                3
                              Desperado
                              {others}

Rush
                              Fly By Night                                                       5.1
                              Fly By Night                [Sector 1]                     Fly By Night               2
                              Fly By Night            
                              {others}
                               Chronicles                                                                                     1
                               Chronicles                                                                                     2

How would I count these per [Artist]. It is difficult since MC wants to treat each Album name as an entity.

Formatting is really bad unless in browser...

Kensn,

Sorry about the lack of response here.  Can you clarify.  Ignoring the {others} albums, how many albums do you consider the Eagles and Rush have each in your examples above?  I'm concluding 6 Eagles and 5 Rush albums.

That is correct sir... I did figure a way by adding all tracks #1, but I would like to count only 1 album for Multi Disc albums in the count.

I have also removed the Disc # from all albums that are not a Muti Disc Album and moved them to a User Field [My BoxSet #] or [My Album Series #] (so in the above example no albums are populated with a Disc #)

Using user field [Album#] = load(v_numalbums_[artist])

Rule = [Media Type]=[Audio] [=1save(0,v_numalbums_[artist])]=1 [=1ifelse(!isempty(compare([Track #], =, 1)),save(math(compare([Track #], =, 1) + load(v_numalbums_[artist])), v_numalbums_[artist]))]=1

This gives me total albums for an artist, using a filter of single artist complete albums, but counts each album in a multi disc album also. Have not worked this out yet.

Here's a simple expression that will return 1 for only track 1 of the first disc in a single disc or multi-disc album:

  compare([disc #].[track #], <=, 1.1)

See below.

This is comparring two values [Disc #] is <= "1" and [Track #] is <= "1" correct? Not the number 1.1. It must be the first or else no disc number and all tracks would count as a positive. 0.2 < 1.1. Also a null return in [Disc #] is ok....

Concatenating [disc #] and [track #] this way creates a numeric floating point string.  MC's expression language is string-based, so this string just acts/appears as a number to the Compare() function.  It doesn't matter if [disc #] is empty or not, as the end result of the concatenation will contain a string that looks like a valid floating point number.

ok...  so Disc # 1 . Track # 3 will be a floating point number 1.3 and this is compared to floating point 1.1?

Then Disc # null . Track #3 is .3 and will produce a positive count being compared to 1.1

What am I missing...

I'm sorry, I gave the items in the wrong order, not thinking.  Use:

   compare([track #].[disc #], <=, 1.1)

track 1 disc <empty>   = 1.        <= 1.1  so TRUE
track 1 disc  1              = 1.1      <= 1.1  so TRUE
track 1 disc  2              = 1.2      >   1.1  so FALSE
track 2 disc  1              = 2.1      >   1.1  so FALSE
track 2 disc <empty>   = 2.        >   1.1  so FALSE
