Sure!
I should mention that the bits of script I posted are not exactly polished. Rather they were made to do one thing, then modified to do something else, but it's easy to see how they could be neater so I'll get on that.
Anyways, here are a couple of albums!
First, there's the Al Di Meola, John McLaughlin and Paco De Lucia album (files have a total of 4 different artists in the artist field, each of them respectively and one for the "band") :
Then here's a Various Artists album. You can see artist ($meta(artist,0)) shows up after the title of each track.
In both of these albums, the artist shown in the header is simply [%album artist%], though if missing, foobar fetches %artist% instead.
