I recently purchased a car that has XM radio and there are a ton of great stations to choose from.  But how to keep track of them all?   So I printed this comprehensive XM Channel Lineup and I keep it in the glove compartment.  This enabled me to pick my favorites and program them into the radio buttons, and then I can always check this list for others that I'd like to try.  There's a couple of great kids stations; and then you can get 60's 70's 80' & 90's; Country; Rock; Top 40; you name it!

It's just a little thing - but it really comes in handy.  I'd always remember that I wanted to print it out when I was already driving somewhere.  But now I've got it with me all the time.
