No music for us while packing either. We primarily do audio books on the road, makes the miles go faster, mostly mysteries. I have a radio that has in addition to CD and regular and HD radio takes thumb drives and SD cards. I keep an SD card in all the time full of fast Bluegrass picking always good when your getting a little sleepy. Then I have an array of choices on thumb drive from oldies rock to comedy sketches depending on our mood if we don't want to do a book or we finished one with a few more miles to go for the day.
I check out audio books from the library and rip them to the computer then copy them to a single MP3 CD or a thumb drive so we don't have to juggle CDs every hour.
