We are starting to see some mainstream music artists use QR codes in advertising and packaging but this is only the beginning. The future will involve much more "collaboration" between music and traditional adverting and a model will emerge that brings value to everyone (music artists, brands AND mobile consumers). QR codes will be a fundamental new catalyst transmitting music from the physical world to a mobile digital one.
Here are some examples of Taylor Swift and Soulja Boy using QR codes and an awesome VIDEO example below from Japan.
his QR code marketing campaign from Leo Burnett Hong Kong was designed to promote alternative music label Zoo Records in Hong Kong. By carefully placing visuals of an array of animals, comprised of download codes, people could take cell phone pictures of the animals and stream new music to their mobile devices instantly. This campaign resulted in sold out records, immeasurable street cred for Zoo Records, and the widespread dispersal of an underground sound.
