Note: a %format string can be used for formatting only the track title. It cannot be used for formatting within the album hierarchy http://forums.rockbox.org/index.php?topic=9570.0
First of all sorry for this double post. I didn't see this thread as I quickly browsed the forum. This is exactly the same topic.
I think you are perfectly right. By doing something like
%format "fmt_mytitle" "%s - %d" title year
the year is shown correctly in the title.
I also tried something like
%format "fmt_year" "(%i) %s" year album ? year > "0"
"Artist Year" -> artist -> year = "fmt_year" -> title = "fmt_title"
This resulted in an output of:
(1995
So in this case the string "album" could not be read.
I hope that in future versions this gets implemented, since it would enhance browsing in the database a lot.
Thanks for your help.
