I can buy a DRM-less lossless music file that will play as many times as I like, on any device I own, for a reasonable price, without having to deal with a crappy and/or buggy distributor-specific app, or being dependent on the distributor's infrastructure being available, the distributor still being licensed to distribute the music, or the distributor still being in business at all. If this works for music, it can work for TV and film as well.
