Thats even more interesting because mp3 wasn't the first digital music, it just had better file compression than previous formats so it made portable digital music players and sharing files over the internet more feasible.

I would have thought the creator was inspired by previous portable music inventions like radios, cassette players, cd players, etc...

weird that he would say the idea came from watching star trek and not from just looking around at the already existing technologies of digital music and portable music and saying "these could go together if I could just make the file sizes smaller"
