Maybe.. but someone thought that this exact format is better for kids to listen to music / audio books / podcasts from, a device that doesnt need internet access, you download what you want and need. Some people also noted (I think it was this device havent tried it) you can open the device up and put in a new SD Card to increase capacity.

On a roadtrip I doubt this stops playing music…
