Need additional cataloguer, like
http://www.collectorz.com/music/ or http://www.ableapples.com/melomania/,
and the MediaMonkey would be an ideal program. With lists of musicians, their dates of birth and instruments, music label and many other fields.

check with a scripter to find out if they will port the involved people tag to one of the custom fields for you.
:)

In the tags file for musicians who participated in the recording, there is only one field. I want this, if it possible: add new column with musicians. Example:

Artist Title Musicians

Pink Floyd Speak To Me - Breathe In The Air David Gilmour, 06.03.1946, guitar,
Pink Floyd On The Run Roger Waters, 06.09.1943, bass
Pink Floyd Time Richard Wright, 28.07.1943-15.09.2008, keyboards
Pink Floyd The Great Gig In The Sky Nick Mason, 27.01.1944, drums
Pink Floyd Money
Pink Floyd Us And Them
Pink Floyd Any Colour You Like
Pink Floyd Brain Damage
Pink Floyd Eclipse

[b]Column "Musicians" linked to the album, but not with the song[/b].
Information for column "musicians" can takes from: 1)tag "Involved people", 2)special file with information about musicians (something like a independent of tag library, with own associations with a particular album). In case 1 we need to introduce a special syntax for tag "Involved people", for example:
[i]David Gilmour, 06.03.1946, guitar; Roger Waters, 06.09.1943, bass; Richard Wright, 28.07.1943-15.09.2008, keyboards; Nick Mason, 27.01.1944, drums.[/i]
symbol ";" - a sign of the transition to a new line in the column "Musicians".
