I had Sirius years ago but dropped it because I had a job where I couldn’t listen at work and ended up just listening to Rush Limbaugh and local sports talk. It’s a decent service if you are really into music.
That being said, I have a friend who had a free subscription and let it lapse. About 2-3 weeks later they called and offered it to him for like $5/month though w/o the “premium programming.” So if you like it...hold out and you’ll get a pretty good deal.
