XM radio, is it really worth it?

I have had xm radio for a few years now in my truck and my dad also has a portable using that he loves. We all have out favorite channels that we listen to. I usually listen to 20 on 20 where the xm subscribers votes on top 20 songs and also the hip hop stations. I also listen to it online sometimes as it comes with a few oinline subscription when you have a regular subscription. I also have directv and alot of the channels come with our directv service. I have it hooked right up to my sat ready pioneer cd player so its all integrated into my truck. I am anxcious to see what happens with this merger with sirius and what programing will be combined together.

My commute is 60+ miles each way. I definitely enjoy XM, especially since I drive mostly through rural areas where radio stations fade in and out. Having the constant satellite signal is definitely a plus for me. Plus, I have a few favorite XM channels that I like to listen to.
