I rarely use my Sirius subscription in my car. Maybe a handful of times per month, I do like having it but am starting to struggle with justifying the cost. I've been toying with the idea of moving to the internet app. I have a Bluetooth connection in my car and can stream music easily. Data used should not be an issue. Anyone using Sirius this way? Or do you prefer running with Pandora, IHeartRadio, Spotify, etc?
