The price is a great deal at the moment, if songs come out that are available for say 1 Opus each, and you have picked up 1000 of them for $50.
That's 1000 songs for 5 cents each. When you look at the average cost of songs and albums on Itunes, and they are aiming at an Opus being a whole track rather than a song, then you can see the potential the coin has in the future.
