People who want to take their own tunes into their cars have a couple of new opportunities, including one that'll let you play digital files in vehicles that don't normally have the capability.
Taking along your own tunes is nothing new, of course. People have been cooking their own programming since the days of tape cassettes and even 8 Tracks to a certain extent. But with the advent of MP3 files, which can pack lots of music into a tiny amount of storage space (at the cost of "dumbed down" sound quality if you compress them too much), there has never been more flexibility, especially when you add to the mix such things as hard drive-based car audio systems.
