My Subaru came with a 3 month subscription to SiriusXM and there was plenty of repetition
I'm guessing only an independent station, such as KVMR in Nevada City, CA is likely to be free of the afflictions described in this thread..
They can be listened to online as well as "on air".
This particular station is very liberal in terms of its news/public affairs content. so some will find this more than enough reason to avoid it.
They offer a very wide selection of genres so I'd strongly suggest consulting their program guide , unless one's tastes are extremely eclectic.
