Say you’re selling copies of your CD (like this one for my nephew Robert’s San Fran band, The Chop) but a potential fan asks, “Yeah, but what do you sound like?” Wouldn’t it be cool if your CD had a flap that played a song when opened? If this doesn’t exist, count on it, since we already see tune-playing chips on greeting cards. Btw: Here’s the song “The Chop With Love” to play.
