Nice article! Can't say I understand all of it yet, but I'll get there (XML is a little new to me). Anyway, I was intrigued by this: ""Smart" playlists have the additional keys Smart Info and Smart Criteria, which contain base-64-encoded data that specifies the smart playlist." I've tried decoding the 'Smart Info' and 'Smart Criteria' keys, but I don't get easily understandable results back. The 'Smart Info' generally returns nothing, and the 'Smart Criteria' returns something like this (for one key): SLst ( Dá ÉT¼@‘» á ÉT¼@‘» D1 1 I'd really like to understand how to decipher these fields, because I'm not happy with the built-in Smart Playlist evaluations, and I'd like to program an app or script that will give me more range in making my Smart Playlists; can anyone help me with this? Thanks!
