As an XM listener and stockholder, I agree with the increase since they have expanded their channel selection, they have grown their customer base and now it is time to start making money. If you don't have either XM or Sirius, I would suggest renting a car that has it and give it a try. FM will never be the same.
I haven't bought a CD in over a year since getting XM. I also record directly to my MP3 player from my XM Roady and have music for running or working out.
