Marc Estabrook has cystic fibrosis, which can make breathing difficult.

Playing the piano helps him get through the tough times.

When the Make-A-Wish Foundation approached him about granting a wish, Marc said he wanted to record a CD of his own music.

A foundation volunteer who works at Starbucks heard Marc's music and got his songs on the stores' holiday playlist.

"The first time I got the email saying this is going to come out in Starbucks, I was like no, not me," Marc said.

Marc is not making any money from the CD. His mom hopes people who enjoy it will donate to cystic fibrosis research.
