A lot of people get hooked into both because of cars offering the first year of service for free. I know people on both sides that are now subscribing because of those offers. Personally, I hate modern pop and really despise commercials so the natural choice for me is XM. It sounds like you need a mix of both unfortunately.I tend to listen to alt rock I have been comparing ethel to alt nation. My concern is
ethel plays too many rare tracks by artists I dont know
alt nation plays the same MTV songs over and over I can only hear AFI and Fall Out Boy so many times not my cup of tea.
Also, xm has more subs but NPD released their retail numbers and at retail people are picking sirius. Are xm users people stuck with it based on the car they own, xm is built into GM, Toyota, and Honda.
