So my grandpa has been legally blind for my whole life and has very little vision, (he can tell the difference between big shapes and he can only read very very large text). About a year ago he had a stroke and lost the ability to communicate. (He is unable to talk at all, and is unable to create sentences when using pen/paper or a letter chart (he is getting better though :) ). I am wanting to get him some music to listen to and have successfully made a list of artists he likes from the 50s (Johnny Cash, Patsy Cline, George Jones, Ray Price, Elvis, Red Foley, Jim Reeves for those of you who were wanting to know (also feel free to make recommendations based on these!)) and I am looking for a way to be able to let him listen to these.

He has an ipad and uses apps like Proloquo2go to help tell us things so I am mainly looking for a solution on an ipad. (I have thought about getting one of those screenless ipod shuffles but the buttons might be a bit too small for him (he has a lot of issues with movement) Is there any good apps that would give him the ability to listen in a simple big interface? He doesn't need to choose songs, simply listen to a rotation and be able to pass a song or pause/play.

Any recommendations would be greatly appreciated.
