another strange question from myside ... consider an album where a couple of soloists are present (could also be artist or any other tag field). Some tracks don't have any soloist field; others have one or more soloist. A soloist's name can appear on more than one track. An example, four tracks:
TRACK=1 ALBUM=Tabula Rasa TITLE=Fratres SOLOIST=Gidon Kremer SOLOIST=Keith Jarrett TRACK=2 ALBUM=Tabula Rasa TITLE=Cantus In Memory Of Benjamin Britten TRACK=3 ALBUM=Tabula Rasa TITLE=Fratres TRACK=4 ALBUM=Tabula Rasa TITLE=Tabula Rasa SOLOIST=Alfred Schnittke SOLOIST=Gidon Kremer SOLOIST=Tatjana Grindenko
Now, I would like to get a list of all soloists present on that album, without dublicates. The example would led to:
Gidon Kremer, Keith Jarrett, Alfred Schnittke, Tatjana Grindenko
What I have so far, is
There I'm stucked. I don't know how to remove the dublicates and don't know how to put nice separator between the single names.
Could you help?
