Startup Idea : Ged rid of CDs

All of us have lot of music CDs, but today we don´t have PCs with CD drives anymore so we actualy can't play these CDs or make a copy of it or convert it to mp3 for our mobile devices. Basic idea of solution is to make a service that takes you a CD and gives you mp3 licence in some music store (as itunes, amazon,...) This service has great marketing potencial and brings new clients to music store. Why should I buy my music somewhere else if I have all music in one music store and I am used to use it.
