RhapsodyX... Since last.fm is so awesome, and it turns out Rhapsody gives you RSS feeds of recently listened-to tracks, I wrote a Status Item (that is, a program that resides in the menubar) that will scrub those feeds and submit them to last.fm. I've called it RhapsodyX and it's in a pretty usable state at this point, so I've decided to release it to the Internet.
Version 1.01n: Fixed a crasher for Tiger users, and problems with URL downloading. Whoops!
