Thanks a lot for looking at this, Nila! I'll try to clearify: The plugin will go through the collection in a pre-determied order (preferably Genre/Artist/Album) and give each post (album name) a unique number, starting with 1 on the first and going all the way up (to almost 3000 in my case). It will then create play lists based on that number, so I can export them (maybe that's not necessary, maybe we can just use a field not used for anything else, like comment 2 - but I'm afraid it will play 2, 12,20, 21 and so on in that case - if we don't put something in fron of and after, like this: $1$, $2$, $3$. In that case it might work, but I'm not sure).
Anyway, the whole point being that I can print out a list afterwards with genres, artists and album names (by using a smartlist that only prints out the first track of each album, but without track name and number - only genre, artist and album. I have one like that at home, but right now I'm on a Christmas visit to my parents). Then that list can be used as basis for calling up the play lists from IR remotes around the house. Right now, if I press "666" I get Mercyful Fate's "Don't Break the Oath" for instance.
Do you follow me now?
