I just heard Rachel Steele on SiriusXM Classic Rewind mention that SiriusXM Radio is having a free trial period online. Just tested it out (Even though I myself have a subscription) and sure enough, the Online Player is working without a login.
I can’t recommend SiriusXM radio enough. If you Love Radio, Hate Ads and are already paying for online streaming music somewhere else, give this a listen and compare.
Some of my favorite Channels are Classic Rewind, SiriusXM 1st Wave, SiriusXM The Bridge, and SiriusXM Big 80s on 8
