Right at the top of the Pandora player you can click to share to twitter, facebook, email and gift. The first time you click on twitter or facebook, you'll get a screen that asks you to allow hte connection.
Here's that the resulting posts look like.
I like how the facebook post includes a music player that lets you listen to the music right there.
You can customise the message too prior to sending it out.
Email just sends out and email and Gift sends a link to a station that you can create like a mixtape. ;-)
If you are interested in listening to Pandora internet radio here are two of my stations:
- Imogen Heap Radio
- Royksopp Radio
