Do what now? I have to pay USD$3.00/month to listen to my playlist? Thanks, but no thanks, guys.
UPDATE: After doing some more reading, it now appears that I can still play the songs on my playlist provided that (a) they're available as full-length tracks and not just 30-second previews and (b) I don't mind either listening to my entire library in the order that I created it and further (c) I'm okay with going to my Last.FM page at the end of each song and clicking the PLAY button to hear the next song. Or I can listen to "My Library," but that's a can of worms I'm not looking to open right now.
