A good question. However...I have long been wary of music that is only in digital format. It sounds great for sure...but do you really own it and what exactly are your rights to using it. Particularly if it is on a cloud server. What happens if it fails, goes bankrupt, or compromised. What happens if your down loads on your player get corrupted, or you lose it. With a physical format these are not issues (except stolen or damaged). Just food for thought.
