I remember this being a concern around when mp3s started to become popular–it's quite amazing how far we've come since the age where an mp3 would soak up an appreciable amount of CPU and saturate an internet connection seemingly forever while downloading. I just started playing an old mp3 file on my new-ish MacBook and was surprised that it was using 15% CPU...before I realized that it was actually loading it from the cloud storage that holds my 7000 song/50gb music library for next to no cost (it dropped to 1% CPU moments later after it had buffered)–never mind having subscription access to essentially all the world's music.
