Other posts might suggest that you "listen to the radio." You should only listen to the radio long enough to remind you how awful the radio is. You basically have three choices on the FM dial these days: you can turn on a top 40 station and hear the newest Taylor Swift song, you can turn on a country station to hear a slightly less new Taylor Swift song, or you can put on a classic rock station and listen to some over-the-hill DJ tell you how awesome it was to see Journey live back in the day. If you don't have to foresight to get that iPhone connected to your car speakers, or, God forbid, your phone dies during the arduous highway trek, do yourself a favor and just listen to the music in your head. It will sound better and help you hang on to your sanity that much longer.
