As I posted earlier, SilverSpider Play List 1.2 has some major new features, including the ability to specify images to be used for specific albums, auto-pruning of the play list file and the ability to override the Artist name when querying Amazon.
Check it out and let me know what you think.
One note, it will probably be a while before I release another version, as I have accepted a new job, and will be pretty busy for a while. But, please send your feedback and I will keep track of it for future revs.
