Giveaway -- five 1-year and five 3-month Slacker Radio Plus subscriptions

In a recent column I wrote about the Slacker streaming music service that lets you create "stations" that stream only your favorite type of music. And I highlighted a new feature of their Slacker Radio app for iPhone, iPod touch, and iPad: the ability to cache songs for offline listening. But the caching feature requires a Slacker Radio Plus account. I have good news: I'm giving away five 1-year and five 3-month subscriptions to Slacker Radio Plus. That's nearly a $50 value for the 1-year subscription and $15 for a 3-month subscription. Post your e-mail address here, or use the contact link to send me a message, and I'll send you a code for a free account. I'll send to the first 10 people who respond, giving away the more valuable accounts first. (Note: This offer isn't open to employees of iPhone Life or to our bloggers.) Thanks to Anders of Slacker for his generous offer.

[Thanks, everyone, for your participation. I've now given out all of the gift certificates.]
