Amazing story, great Product! You grandfather is giving you realtime feedback (ex: his request for a music player).

Most projects on Kickstarter and Indiegogo don't even have a fully functioning product, whereas, you already have your product and your 1st customer, so why don't you take this product to the next level, and sell it to the wider audience of blind people?

You will have a tremendous impact on society doing good, and make a decent side-income at the same time.
