Select an image for a playlist

[Uncle Stan]

I would like to assign a custom image to a playlist. As it is, when songs come from different albums they all show up in a spiffy mosaic. However, I would like to be able to emulate compilations & anthologies and use an image indicative of that grouping.

I think this would be handy for identifying playlists of, say, "home-made" Greatest Hits albums or other anthologies/compilations, e.g., The Beach Boys "Spirit of America". I have all the songs, I've made the playlist, I would like to show the album cover or some other art rather than the mosaic of the albums from which the songs were culled.
