I am hooked on Spotify. You can get it free, but you have to put up with occasional ads, or you can upgrade for a nominal fee and eliminate the ads. The app gives you access to nearly every piece of music ever recorded and commercially available. That's EVERY piece of music (with the notable exception of the Beatles, because rights to their music is in private hands, I think Michael Jackson's estate?). You can create your own play lists and you can link to other peoples lists, and there are dozens of lists named "driving music". You can access the music from any smart device, including iPod. I think this is the future of the commercial music industry.
