I'm very out of touch with hAudio development, but this touches on  
something I've not seen addressed lately. In the context of hAudio  
what is the difference between a ‘Playlist’ and an ‘Album’? How is an  
‘Album’ not just a specialised kind of playlist?

Answers by way of links to previous discussions are fine.

Thank you,
