in order for it to transfer, you need to download audioscorbbler. click on where it says "download" at the top. it should say this on your right:
"The program: Audioscrobbler
Audioscrobbler will send the name of every song you play on your computer to Last.fm. This effortlessly populates your profile to play radio you like and make personalised recommendations!"
but you're not alone though 'cause i'm still tryin to figure it out too.
