QR Music is an app that you can use it to scan any ean8/ean13 or upce/upca barcode and then convert barcodes to music.
It is full of fun. After trying it, you might be crazy about scanning barcode no matter where you can find, like product on market, books on your desk, even the shampoo in your toilet.
And then you will find you are surrounded by music not the simple and boring barcode.
