I've been listening to a free trial of XM Radio in our Honda Element during my 60 minute commute. I appreciate the variety and range of easy access music that gives me ideas for worship services and sermons. I've learned of a few more new bands I to whom I wish to give a deeper listen. But it's still not worth $13-14 per month.
My iPhone is the free link to a much broader spectrum than XM radio. I have Pandora and CBC Radio free apps on my iPhone--and I'm sure I could find more. Since I've expanded my contacts on Twitter to more music-related forums--I know I can dig around my Twitter contacts for ideas for music. I am not at a loss for expanding my musical universe. And there's always the good folks I know at Trade Root Music who can fill me in on great music ideas. I will not be at a loss for music once the XM trial expires in March. Thank goodness XM doesn't have a credit card number for me anymore to renew me without permission.
