Which type of music player would be easiest for my mom to control?

How can I set my mom up with something that is easy for her to use so she can listen to music in her assisted living bedroom? The radio channels in her little town are not very good, and I would like to tape the music she loves so that she can turn it on easily. Is there an easy iPod or similar device that she could just press one button to control or play the music? This would be sooo helpful. Thank you!!
