My own use of Digital Sound (wav, mp3, ogg, and etc) actually are asking "my little partners" (cute children not just student) to download it and then keep listening or playing it while wrote the composition in a music book... that way they will keep learning about writing a composition, and reading pattern, eventually they will wrote their own later (even if those composition are took part from many compositions that they have heard and wrote). I am sure they will keep Progressing...
