I'm here. :-)

About the multiple songs thing. For some odd reason, LimeWire can only launch one song at a time. So, to make a playlist, you have to manually add them by browsing your hard drive. By default, your shared folder is C:\Program Files\LimeWire\Shared. I know this is a serious shortcoming, but it may be changed in the future. Integration of a media player is being planned for a future release. It would be great if it had a playlist, too! :-D

Do you know Java? I don't, but enough people have complained about this that it might be worth it to add this feature. If anyone is working with limewire.org and the open-source code projects, this would be a nice little improvement to add to your list.
