SiriusXM offers a SiriusXM Internet Radio 30-Day Trial for free when you fill out a short form. That's the best free trial deal we've seen from SiriusXM since early April, when it offered a 60-day trial for free, although it was for car radios only. This trial includes access to every SiriusXM channel (including Howard Stern) and can be listened to on a computer, iPhone, iPad, iPod touch, or many Android devices.
